How secure are uPVC doors?

Mon, 27 Apr 2026 22:57:13 GMT

Modern uPVC doors are more secure than you might think. Learn how they work and what makes them secure, as well as their limitations.

How secure are uPVC doors ?

The short answer: uPVC doors are very secure, as long as you choose the right specifications.

A modern uPVC door with the right locks is very secure. It can resist forced entry, handle the British weather and last for years.

However, not all uPVC doors are made the same. The main difference between a secure and a vulnerable door commonly lies in the lock cylinder.

What makes a modern uPVC door secure?

The security of a uPVC door comes from several elements working together.

The reinforced galvanised steel frame gives structural rigidity and resistance to force. Multi-point locking mechanisms, meanwhile, fire multiple hooks, bolts and rollers into the frame. This typically creates at least five contact points, delivering enhanced security compared to single-point locks.

uPVC doors often have toughened or laminated glass that does not shatter when struck, preventing an intruder from simply breaking the glass and reaching through.

Finally, it's also worth noting that quality uPVC doors are internally glazed as standard. This means the glass is secured from inside the door rather than from the outside. As a result, it's all but impossible to pop out the glazing from the exterior and reach through to operate the handle.

The weak point: why the cylinder matters

The main weakness in older uPVC doors is the euro cylinder lock. This is the barrel-shaped part where you insert the key, found in the middle of the handle.

Standard euro cylinders are vulnerable because a section protrudes beyond the door face. If this exposed section is gripped and snapped with the appropriate tool, the cylinder breaks within seconds, rendering the multi-point locking system useless. Lock snapping is a known burglary technique used across the UK.

Anti-snap cylinders solve this problem. If someone tries to break them, only the front part snaps off, but the lock inside stays secure and keeps the door locked.

The top standard is 3-star-rated locks. These are tested against snapping, picking, drilling and bumping.

If you have an older uPVC door or are unsure about your lock, you can take some simple steps to improve security. Look for markings like "TS007 3-Star" or "SS312 Diamond" on your lock. If you do not see them, your lock may fail to meet current standards.

Upgrading your lock is an easy and affordable way to make your door much safer. A local locksmith can help you choose and fit an anti-snap cylinder.

Security standards worth knowing

PAS 24 is a standard for doors that are harder to break into. Doors with this rating have been tested using tools such as crowbars and chisels. It's one of the best independent measures of door security in the UK.

Secured by Design is a police-backed programme that approves products proven to offer good security.

Document Q sets the minimum security standards for doors in new homes in England. It does not apply to replacement doors, but you can still use its standards as a guide. Ask your installer whether the door meets or exceeds Document Q to make sure you're getting up-to-date security, even if it is not required by law.

How Calder Windows approaches door security

At Calder Windows, we prioritise security. All our uPVC doors come with Yale multi-point locks and 3-star euro cylinders, which meet the highest security rating in the UK. Our locks are tested against snapping, picking, drilling, bumping and pulling.

Both Yale and Winkhaus locks, which we use in our contemporary range, are accredited by Secured by Design. With more than 70% of UK burglaries involving a door, we use Yale 3-star cylinders for superior security.

There is no minimum security standard for replacement doors. Installers are not required by law to fit locks or hardware that meet the most rigorous security benchmarks.

For homeowners, this means the onus is on you to choose high-quality, independently tested products – and a trustworthy fitter – to keep your home properly protected.

When a composite door might be the better choice

For most homeowners, a modern uPVC door provides more than adequate security. However, if maximum security is the priority, a composite door is worth considering.

Composite doors are denser and can handle more force, which is helpful if someone tries to break in.

A composite door is usually 44mm thick, compared to 28mm for a standard uPVC door. Its strong core, tough outer layer and solid build make it harder to break. Composite doors look like traditional timber, do not need painting, and come in many colours and styles.

A uPVC door with a Yale 3-star cylinder and multi-point locking is a secure and sensible choice. But a composite door is even stronger, so would suit those looking for the very best security.

What to put in a bay window: 7 beautiful and practical ideas

Mon, 20 Apr 2026 13:53:01 GMT

A bay window provides valuable extra space – but what should you do with it? Explore practical and decorative ideas to put yours to good use.

Stuck for inspiration on what to do with your bay window?

Bay windows can be a beautiful and timeless addition to any room. They add heaps of architectural charm, panoramic views and abundant natural light. If you're lucky enough to have one in your home, you'll know just how much larger and brighter they can make a room feel.

Not only that, but a bay window creates an ingenious little functional space in your room that can be utilised in all kinds of exciting ways.

But there's the rub. Bay windows promise endless possibilities – and where there are endless possibilities, there are endless reasons to be indecisive.

Don't worry. We've got you covered. Here are seven of the most creative and practical ways to put that space to good use.

Seven creative bay window ideas

1. Make a haven for houseplants

Bay windows let in copious sunshine. Why not take advantage of it by setting up your own indoor garden?

Sun-loving plants will thrive surrounded by light and with ample ventilation. And they'll look good, too. The bay's deep sill and high frame allow space for dramatic, layered displays and beautiful hanging plants without compromising on living space.

With a little watering and TLC, you can create a green sanctuary that will look spectacular from indoors and out.

2. Create a cosy reading nook

Love books? Indulge your passion. Turn your bay window space into the dreamiest little reading nook with plenty of shelving and a cosy armchair or window seat.

Creating such an inviting space that's dedicated to relaxation can transform any room into a tranquil oasis. Think comfort and lighting – you'll want plenty of soft furnishings, surface space and a thoughtfully placed lamp for your evening wind-downs.

3. Set up a light and airy workspace

Using your bay window as a workspace is a great way to make your space work harder. In effect, you're creating a semi-separate room within a room.

Here are some tips to help you get it right first time:

��️ Choose a well-fitting desk and use under-desk storage to maximise space.
✨ Consider sheer curtains or roman blinds to avoid screen glare when necessary.
�� Room dividers are a great way to increase privacy, should you prefer.
�� Of course, don't forget to add some homely touches to make your workspace truly yours.

Just imagine: you can spend your day working in sunlight, with great views of your surroundings. Apart from its space-saving advantages, you'll also profit from the mood and productivity-boosting benefits of all that extra natural light.

4. Install a window seat with hidden storage

Need more space? Here's an idea: create a multi-functional space by installing a custom-made window seat. Inside, you can include a hidden space for hard-to-store items, such as pillows, throws or children's toys.

Along with creating an inviting chill-out spot, installing a made-to-measure piece of furniture like this gives your room a beautiful, well-finished feel. It adds character and charm to your home while keeping your spaces clutter-free thanks to its ample hidden storage.

Furnish the space with plenty of cosy cushions and you'll have an irresistible spot to sit and watch the world go by.

5. Build the perfect breakfast area

It's the most important meal of the day, so why not give it the attention it deserves?

A custom-made U-shaped bench built into your bay will transform your window into an idyllic little breakfast area. Throw in a round pedestal table and it will look even better.

The result: a multi-functional space that doubles up as a cosy homework spot or crafting station. Install it in an east-facing room for the chance to enjoy your coffee in the morning sunshine. Or customise a west-facing space and you can soak up the last of the day's light for your evening projects.

6. Turn your seating towards the view

This one's simple – just place some well-chosen furniture into the bay window area. A window-facing loveseat or a couple of snug armchairs will create a comfortable little conversation corner.

This is a great way to draw attention to your beautiful bay window and make it the focal point of a room. It creates a gently partitioned area within your room, ideal for slowing down and catching up.

7. Looking for privacy? Make a statement with the dressings

Want to enjoy the period charm of your bay window but with a little more privacy? Now's the time to let your imagination go wild with the window dressings.

How about plantation blinds, roller blinds or Roman blinds? Or perhaps some custom-tracked curtains? These are all brilliant ways to accentuate the striking architectural shape of your bay window while allowing for privacy and light control.

You can be bold and brave with colours and fabrics, or you can keep it sleek with a simple blind. It's totally up to you.

In any case, dressing your bay to reflect your personal style can be a fun and effective way to add a focal point to the room.

Why invest in a bay window?

Are you considering adding a bay window to your home? Are you ready to upgrade an old one?

Investing in a new bay window installation can:

☀️ Increase the natural light in your room
�� Improve ventilation
�� Offer better views

How to clean aluminium window frames

Mon, 13 Apr 2026 18:11:11 GMT

Aluminium window frames are low-maintenance, but they still need care. Follow our straightforward guide to keep them clean and looking their best.

Aluminium window frames are popular because they're easy to maintain. Unlike wooden windows, they don't rot, warp or need repainting.

That said, they do need some mild care. Cleaning your frames regularly helps them look good and last longer.

So, how do you go about keeping them clean and in good nick? Follow our step-by-step guide and you'll have shiny, new-looking aluminium windows in no time.

What you'll need

You don't need any special products for a basic clean. In fact, you probably have most of what you need at home already.

For regular cleaning, gather:

Warm water
A little mild washing-up liquid
A soft cloth or non-abrasive sponge
A dry microfibre cloth
A soft brush for corners and tracks

If you have tough stains or oxidation, you can also use white vinegar, bicarbonate of soda and a spray bottle.

For very dirty frames, a commercial aluminium cleaner can help, but always test it on a hidden spot first.

What to avoid

It's just as important to know what not to use as it is to know what works.

When cleaning aluminium frames:

Never use bleach, ammonia cleaners or anything rough. These might damage the protective powder coating. Once that's gone, the frame is much harder to look after.
Avoid wire brushes, scouring pads and rough cloths.
Don't use high-pressure washers , as the strong water can push moisture into the seals and cause problems later.

Stick to soft materials and gentle cleaners to help the finish last longer.

Step by step: the standard clean

This cleaning routine works for most aluminium frames and covers everyday cleaning needs.

Step one

Remove loose dirt. Use a soft, dry brush or cloth to sweep away dust, cobwebs and dirt from the frame and nearby areas. This helps prevent scratches when you clean with water.

Step two

Make your cleaning solution. Add a few drops of washing-up liquid to a bowl of warm water. You don't need much soap.

Step three

Wipe the frames. Dip your soft cloth or sponge in the solution and clean the frames from top to bottom. Keep the cloth damp, not wet, and rinse it often to avoid spreading dirt around.

Step four

Rinse well. Use a clean, damp cloth to wipe away any remaining soap from the frames. If soap dries on the surface, it can leave streaks and attract more dirt.

Step five

Dry right away. Use a dry microfibre cloth to get rid of any remaining moisture on the frames as soon as you finish rinsing. If water sits on the aluminium, especially in hard water areas, it can leave marks or spots.

Dealing with stubborn stains and oxidation

If your frames haven't been cleaned for a while or have stains, warm soapy water might not be enough.

For tough stains, mix equal parts white vinegar and warm water in a spray bottle. Spray the area, then gently wipe in circles with a soft cloth. Rinse well and dry immediately.

If you see a dull, powdery or grey coating on the frames, this is oxidation. You can make a paste with bicarbonate of soda and water and gently rub it on with a soft cloth. Don't scrub hard and be sure to rinse well afterwards.

For heavy oxidation, a commercial aluminium cleaner works best. Always try any new cleaner on a small, hidden part of the frame first, though.

Cleaning the tracks and hardware

The tracks are often the part that people forget to clean. Dirt and grit can build up in the channels, making windows hard to open and wearing out the moving parts.

First, use a vacuum cleaner with a narrow nozzle to remove loose dirt from the tracks. Then use an old toothbrush dipped in warm, soapy water to loosen any stuck dirt. Wipe with a damp cloth and dry thoroughly.

After cleaning, apply a small amount of silicone-based lubricant to the moving parts and hinges to keep the windows working smoothly. Don't use oil-based lubricants, as they attract dirt and can cause more problems later.

How often should you clean aluminium frames?

Cleaning your frames every two to three months is enough for most homes.

If you live near a busy road, in a polluted area, or get a lot of wind and rain, you might need to clean them more often.

Clean the tracks every three to six months, or whenever the window feels hard to open.

Wiping down the frame once a month between deep cleans takes only a minute and helps prevent dirt from building up.

The benefits of aluminium windows

Are you considering investing in aluminium windows? As you can see, keeping them shiny only takes five simple steps – a doddle!

They're so easy to clean because the material is made to handle everyday use.

What's more, aluminium is strong, so frames can be made slimmer than uPVC ones. Slimmer frames mean more glass, more light and a modern look.

Quality aluminium frames have a built-in barrier that separates the cold outside from the warm inside. This helps keep heat in and makes them as energy efficient as other types of frames.

Finally, aluminium does not rot, warp or rust in normal conditions. The powder-coated finish is tough, resistant to sunlight and available in many colours, including options with different inside and outside colours.

What are the different types of casement windows?

Tue, 07 Apr 2026 22:47:29 GMT

Don't know which type of casement window is right for you? Read our comprehensive guide to the different casement window styles.

Have you noticed your energy bills spiking over the past few months? Are leaky windows letting in a lot of noise pollution?

There are many reasons why homeowners might look to replace old windows, from broken frames to simply wanting to refurbish.

But which type of window should you choose?

In most cases, casement windows are the first choice for UK homeowners. Modern casement windows are secure, energy efficient and versatile – qualities that have helped make them the most popular type of domestic window in Britain.

In this article, we explore the different styles of casement windows, so you can make the right choice for your home and your needs.

But first, let's cover the basics.

What are casement windows?

Hinged at the side, top or bottom, casement windows have a simple but effective design offering maximum ventilation with minimal fuss.

Modern casements typically come with multi-point locking systems, making them very secure. They're energy-efficient, too. Their clever design means that, when closed, the sash pushes firmly against the frame and creates a tight seal, locking in warm air.

The only downside? It can be tricky to choose the right style for your home. Casement windows come in a huge variety of designs, each offering its own distinct functional advantages.

Let's take a look.

The different styles of casement windows

Side-hung casements

As its name suggests, the side-hung casement window is hinged along its edge to swing outwards like a door. It remains the most popular casement style thanks to its modern design, ease of use and excellent energy efficiency.

A good all-rounder, the modern side-hung casement:

Offers clear, unobstructed views of outside spaces
Maximises ventilation and natural light inside the home
Is very durable with minimal maintenance needs

When fitted with internal, multi-point locking systems, this window style provides a high level of security. The side-hung casement's large opening design means it can often also be used as an effective fire escape route.

Top-hung (awning) casements

Awning-style casement windows are hinged along the top, allowing them to open outwards from the bottom. They're a popular choice for tighter spaces, as well as warmer, more humid areas of the home, such as bathrooms and kitchens.

Their top-hinged design creates a canopy effect, offering weather protection even during light rain. Meanwhile, moisture-filled or stagnant air can escape, delivering pleasant, well-ventilated conditions indoors.

When placed higher up, they can deliver excellent ventilation without significantly compromising on security. When closed, they create an excellent, weatherproof seal that prevents air leakage and helps improve your home's energy efficiency.

Bottom-hung (hopper) casements

Hopper casement windows are hinged along the bottom edge and open inwards from the top.

They are ideally suited for smaller areas and lower-level areas, such as basements and utility rooms. Their inward-opening mechanisms allow for controlled ventilation while only creating very limited access from the outside. They're also perfect for spaces where an outward-opening window would create an obstruction to outside areas.

Their space-saving design offers excellent ventilation, energy efficiency and access to natural light in areas where a standard outwards-opening window would be impractical.

Flush sash casements

Flush casement or flush sash casement windows are an excellent choice for both modern and traditional homes. Designed to replicate the appearance of traditional 19th-century timber windows, their sash sits flush within the frame for an elegant, classic look.

Thanks to this historically accurate aesthetic, flush sash casements are often approved for installation in listed buildings and conservation areas.

Much like the side-hung casement, flush sash casements maximise natural light and ventilation around the home. They also allow for clear, unobstructed views of outside spaces and gardens.

While they lack the overhanging lip of a standard casement sash, this doesn't compromise their weather-resistance. The flush sash casement offers superb protection from the elements. These windows are fitted with a double-rebated seal to prevent water ingress and improve insulation.

Modern varieties also house robust, multi-point locking systems inside their frames to keep your home safe from intrusion.

French/double casements

French or double casement windows are constructed with two side-by-side sashes, each hinged at opposing sides.

This opening mechanism means both windows open outwards without a central pillar (mullion) to obstruct the view. Instead, double casements feature a "flying mullion" attached to one sash. This flying mullion moves with the sash when the window is opened.

Many homeowners choose French casements because they offer abundant natural light, a bright, open feel and good ventilation. They're also favoured by those looking to bring a symmetrical, traditional look to their home.

Their recognisable design doesn't compromise on performance either. Modern double casements boast excellent energy ratings, multi-point locking systems and the potential to function as an emergency egress route.

Fixed casements

The simplest style of casement window, fixed casements contain no opening mechanisms. Often installed alongside other casement styles, especially in bay windows, fixed casements are extremely durable and easy to maintain.

While they don't offer ventilation, they do allow for plenty of natural light and unobstructed outside views. Modern varieties are exceptionally secure and ideal for hard-to-reach or decorative areas, such as high-level gables.

Casement window energy efficiency ratings

The energy efficiency performance of a window is typically given as a U-value. This is a measure of how effectively building elements (such as windows and doors) transfer heat from inside to outside.

Another important measure is the BFRC energy rating. This measures heat loss on a ranked scale from A++ (best) to E (worst).

So, when looking for energy-efficient windows, you want a low U-value and a high BFRC energy rating.

A modern, double-glazed casement window will typically achieve an A rating on the BFRC scale and a U-value from 1.2 to 1.4 W/m²K.

Calder Windows' triple-glazed casement windows are rated A++ and offer a U-value of between 0.7 and 0.8 W/m²K. With 43% thicker units for better insulation and increased security, they perform with an impressive 40% better thermal efficiency than standard glazing.

What paint should I use on window frames?

Mon, 23 Mar 2026 21:27:36 GMT

Peeling paint and unsightly frames? Find out the best paint to use on old windows and the right way to prep them for a revamp.

Is the state of your windows affecting your home's curb appeal? Are they looking tired and in need of a revamp?

Perhaps you've noticed peeling, cracking or flaking paintwork, along with soft spots and areas of discolouration. These are all good indicators that your windows are in desperate need of some TLC.

And it's not just about aesthetics. The finish on your window frames acts as a protective barrier against moisture. Once this becomes compromised, damp, mould and rot can quickly take hold, causing much more serious structural damage and costlier repairs down the line.

Preventative measures are always the best option. Unfortunately, however, it's not quite as simple as giving them a lick of any old paint.

Your home's window frames are exposed to harsh environmental changes, direct sunlight and, in the UK, more than their fair share of rain. These are things that ordinary paint just cannot withstand.

To protect your windows properly, you need to make sure you have the right paint for the job at hand. That means factoring in:

Its weather resistance
Its flexibility to withstand temperature changes
Its ability to adhere to the material of your frames

The best paints for different types of window frames

Different frame materials require different paints to keep them protected.

UPVC windows

Things to consider

Designed with a non-porous, smooth finish, uPVC windows need a high-bonding, vinyl-safe and weather-resistant paint. This allows for adequate adhesion and expansion or contraction with temperature changes.

What's the best type of paint for uPVC windows?

Acrylic or polyurethane-based paints are ideal for painting uPVC surfaces. They're flexible enough to withstand environmental changes and sticky enough to bond to the smooth finish of uPVC.

Options include:

Zinsser AllCoat Exterior Paint
Rust-Oleum uPVC Paint

Wood

Things to consider

Susceptible to rot, cracks and warping if not properly maintained, wooden window frames require a microporous and weather-resistant paint. This allows the wood to breathe while protecting it from the rain and sun.

What's the best type of paint for wooden windows?

A durable, flexible, microporous water-based paint is the best all-rounder for repainting wooden window frames. Oil-based enamels offer superior durability for higher-wear areas. However, they're less flexible and therefore more prone to cracks in the future.

Look at options like:

Dulux Weathershield
Zinsser Allcoat Exterior Water-Based Paint
Paintmaster Oil-Based Satinwood Paint

Aluminium

Things to consider

For aluminium frames, it's important to use a rust-inhibiting primer before coating with an exterior-grade, high-adhesion metal paint.

What's the best type of paint for aluminium windows?

After applying your metal primer, use a high-quality acrylic latex paint or epoxy-based paint to protect your aluminium frames. These options are able to withstand thermal expansion and contraction and offer superior adhesion to the window frame's surface.

Consider options like:

Sandtex 10 Year Exterior Gloss Paint
Dulux Weathershield

Tips for getting the best finish

Don't forget the prep

Prepping your window frames properly can make all the difference to the overall quality of your painted finish.

Proper preparation will ensure your new paint adheres properly and creates a smoother, more professional appearance. It can also provide longer-lasting protection against the elements.

Prepping uPVC windows for painting

UPVC requires a thorough clean with warm, soapy water or sugar soap, as well as a degreaser. This should rid the frame of any dirt, grease or silicone residue in preparation for its makeover.

Gently abrade the surface of the frame using fine-grit sandpaper to create a slightly rough surface for the paint to stick. Be careful not to remove the top layer of plastic.

Now, carefully apply masking tape around windows and brickwork to help guard against the inevitable mishaps. For best results, apply a specialist uPVC primer before painting to ensure maximum adhesion.

Prepping wooden windows for painting

Preparing wooden frames can be time-consuming, but it's crucial for ensuring the longevity of your windows.

Start by cleaning the frame well, removing any dirt and debris, before using a scraper to remove any loose or flaking paint.

Check for signs of moisture damage by looking out for any soft or discoloured areas of wood. Rot or mould will need to be repaired and treated before any work continues.

If you're satisfied with the condition of the frame, fill out any cracks or holes with an exterior wood filler. Now, sand down the entire frame to give yourself a smooth canvas.

Carefully apply masking tape to any areas that should not be painted, and use a good-quality wood primer to seal the wood. This will ensure proper adhesion and prevent any tannin stains from bleeding through the paint.

Prepping aluminium windows for painting

For aluminium frames, use a mild detergent or isopropyl alcohol to remove any dirt or grease before starting work.

Check for any signs of rust, removing them with a 1:1 mixture of white vinegar and water. For deeper oxidation, you may need to use an 80- to 100-grit sandpaper to carefully sand it down.

Now, remove any old peeling or flaking paint before lightly sanding the entire frame to create an ever-so-slightly rough surface for the paint to grip. After applying your masking tape, finish prepping the frames by giving them a coat of high-quality self-etching primer or specialised metal primer.

Watch the weather forecast

Repainting your old windows can be time-consuming. So, it's crucial to make sure you plan your labour for when there is an extended stretch of dry weather expected.

Why? Because rain and high humidity can prevent your paint from curing correctly and adhering to the frames properly. This could potentially lead to mould and mildew buildup, blistering or peeling paint and a streaky, uneven finish.

Out with the old and in with the new?

Sometimes, even a good lick of paint can't refresh a tired old window.

If your windows are very worn or damaged, painting them could just mean kicking the problem further down the road. It might make financial and practical sense to replace them rather than invest in repeated quick fixes that don't address the underlying issues.

What's more, old windows typically perform less well than modern windows, even if they're in good condition. Buying new windows could drastically improve thermal efficiency and security – two benefits that may add up to substantial cost savings in future.

How to stop draughts around doors

Mon, 16 Mar 2026 07:35:33 GMT

Do you have draughts around your front door? Learn some tips and tricks to keep the cold air out.

Here in the UK, where cold snaps are common, draughts can be an annoyingly persistent problem. You're doing your best to keep your house warm, when – woosh! – a breeze comes along and sends a shiver up your spine.

And it's not just uncomfortable. Those pesky draughts can make your heating work less efficiently, which in turn can lead to ballooning bills.

Often, you can point the finger of blame at your front door. If it's worn, damaged or improperly installed, it might be letting in more cold air than it should.

The good news is that draughty doors can often be fixed cheaply and effectively.

In this article, we cover some easy methods that require little to no installation, as well as slightly more involved ones. This way, you'll have a range of solutions to try depending on your particular needs and budget.

First steps

Examine the door

Start by closely examining your door. You're looking for gaps between the door and the frame, as well as cracks and gaps in the frame and surrounding masonry.

While you're at it, grab a tape measure and write down the dimensions of your door. These might come in handy later.

As the tiniest gaps can be tough to spot, you can use (with caution) a lighter as a handy draught-finder. Move the flame over your door and around the door frame. Watch out for the flame flickering, as that will indicate a draught.

Don't forget the keyhole and letterbox

Now, this one might sound obvious, but it's often overlooked.

When looking for areas to seal, it's easy to focus entirely on unintentional gaps. But remember: cold air doesn't discriminate.

So, make sure your keyhole cover (escutcheon) and letterbox flap are well-fitted – or install them if your door lacks them. If you do have a letterbox flap, make sure it's still well-insulated.

An escutcheon can be fitted over the keyhole with just a few screws. Easy!

Quick fixes

Cushion draught excluders

Let's start with the simplest option, requiring no installation.

Cushion draught excluders come in many designs and colours, but the basic idea is pretty straightforward.

They're basically long, thin pillows stuffed with a soft material. Place one right at the bottom of your door, and it will cover the gap and help stop cold air from entering.

They're also quite cheap. So, whether you go for a cute dog or a simple cushion, you can tackle the worst draughts at the bottom of your door with little cost and hassle.

And you don't have to stop at the front door. Pop a few extra in your shopping basket, and you can cold-proof multiple doors in your house in no time. Just make sure they're the right size for the width of your doors.

Job done, right? Well, the obvious disadvantage to cushion draft excluders is that they only cover the bottom of the door. You'll need to consider another option if the cold air is entering from elsewhere.

Plus, as they're not fixed to the door, you have to remember to push them into the right position every time you enter or leave.

All said, however, it's a quick and easy solution that could prove very helpful while you set up a more permanent one.

Brush draught excluders

Brush draught excluders are the next step for those seeking a more permanent solution.

Like their cushioned siblings, these tackle the worst gaps under your door. Unlike cushion draught excluders, however, they attach to the door using screws or self-adhesive strips. That means that, once properly installed, they keep doing their job with no need for you to continuously readjust them.

When buying one, try to find one already cut to size to match your door. The alternative is to use a hacksaw and sandpaper to adjust and smooth it to be the right fit.

To install the brush excluder, line it up straight and centred at the bottom of your door. You want it to cover the gap and sit snug against the floor. Don't go too low, as that could make it hard to open and close your door and put too much pressure on the excluder.

Finally, even if your excluder comes with a self-adhesive strip, it's a good idea to use screws, as these provide extra durability. Screws are usually provided.

When done, examine the result of your hard work. If there are any unwanted gaps, loosen the screws, readjust and tighten again.

Self-adhesive strips

Do you need to close gaps further up from the floor? Self-adhesive foam strips are the go-to DIY solution.

These strips usually come in five-metre-long rolls, so you'll have plenty spare when you're done sealing your door. They're usually quite affordable, too.

Applying them is simple. First, you should clean your door thoroughly. This helps the strips stick firmly. Then, use scissors to cut strips to length – preferably slightly longer than each respective side of the door.

Now, peel off a little of the backing paper at one end of the strip and press it firmly to one corner of the door.

Continue peeling and sticking the strip, little by little, as you progress. This helps stop the strip from sticking to itself or elsewhere.

Finally, cut off any excess and repeat on the other sides.

When done, try closing the door and make sure everything fits. If you notice any gaps in one strip, it's best to start again and redo the whole length. Using multiple shorter strips won't seal as effectively, and they might start peeling off faster.

Bigger fixes

Sealant

If you notice gaps or cracks in the actual door, frame or surrounding masonry, sealant is your best bet.

You can buy chalk or silicone sealant. Many experts recommend silicone for outside work, as it's waterproof.

Using sealant is slightly more involved than the other methods we've shared so far. You might need to get your hands dirty, but don't worry – it's not too tricky.

To get started, you'll need:

The sealant gun
Some masking tape
A filling knife or a scraper
A little patience

Gathered all your tools together? Great! Start by cleaning the affected area thoroughly with warm, soapy water. Let it dry completely.

Next, apply tape around the gaps and cracks to protect the surrounding material. Fill the cracks with the sealant, carefully going from top to bottom. Smooth it over with your filling knife.

Afterwards, remove the masking tape and, if necessary, carefully wipe off any smudges.

After waiting for about 24 hours, examine the result to make sure there are no more draughts.

Installing a new front door

Sometimes, the best option is to say goodbye to an old door and replace it with a new one. This might make practical and financial sense if:

The door has warped or twisted – no amount of draught-proofing can fully compensate for a severely warped door
The door is damaged or rotted – deep cracks and rot can't be reliably patched
You can see daylight through the cracks or gaps – this usually indicates that the problem is too severe for standard draught-proofing measures
You've tried fixing it multiple times – if the problems keep coming back, it might be best to wipe the slate clean and start again with a new door
Your door is old and outdated – old-fashioned, uninsulated doors are prone to letting heat escape, with or without draughts

At Calder Windows, we supply a wide range of high-quality doors to customers throughout Yorkshire. That includes replacement composite front doors , which are much sturdier and more energy-efficient than their old, uninsulated counterparts.

Plus, with our top-notch installation and 10-year warranty, you can expect to be draught-free for many years to come.

Based in Normanton, West Yorkshire, Calder Windows is a trusted and experienced supplier of doors, windows and conservatories.

How to get scratches out of glass windows

Fri, 13 Mar 2026 07:40:41 GMT

Windows are hard – but they're not completely scratch-proof. Explore some tried-and-tested tips to get scratches out of glass.

Glass has a reputation for being delicate. But did you know it actually ranks around 5.5 on the Mohs hardness scale? That makes it more resistant to scratching than iron, steel and brass.

However, that doesn't mean it's immune. Dust, dirt, abrasive cleaning tools and even pet claws can occasionally leave scratches on an otherwise pristine window.

If this happens to you, don't worry – all hope is not lost.

In this guide, we cover some tried-and-tested DIY solutions that can help restore windows with light scratches. And for those deeper or more pervasive abrasions, we also look at when it's best to call a professional or replace the window entirely.

First step: assess the damage

The first thing you should do is examine the damage. If the scratches are too deep or cover a significant portion of the surface, our DIY solutions may not be sufficient.

Start by cleaning the window thoroughly with a glass cleaner and a microfibre cloth. You're trying to remove smudges or dirt that could either hide the real depth of the scratch or make it seem bigger.

With the window clean, how big is the scratch? If it covers a large area, it could be too much for simple solutions to remedy.

Next, try the fingernail test. Simply run a fingernail over the scratch. If your fingernail easily catches on the scratch, it's probably too deep for DIY.

Have you investigated and think the scratch seems manageable? The following methods might just do the trick.

Simple solutions to fix scratched windows

Abrasives

Toothpaste

For minor scratches, you might find success with toothpaste. Your best bet is using whitening, non-gel toothpaste, as it has a lightly abrasive texture that's just right for windows.

There's no need for a toothbrush. Just grab a small, soft cloth. Apply a small amount of toothpaste to the scratched area and rub it with the cloth in a circular motion. Continue for a minute or two.

Now, rinse the area with water and examine it. If the toothpaste seems to be working, you can repeat the procedure once or twice more. But if it's no help, it might be time to move on to another method.

Bicarbonate of soda

Bicarb, the famous household staple, has a plethora of uses. It should come as no surprise that removing glass scratches is one of them.

First, mix equal parts water and bicarbonate of soda to form a thick paste. From then on, the approach is quite similar to the toothpaste method.

Apply a small amount to the affected area and rub it in circular motions using a clean, soft cloth for a couple of minutes. Then, wipe the area clean using a new cloth and warm water.

Check your progress. You can repeat the process a few times if necessary.

Abrasives not doing it?

There are other substances you could try to use in a similar fashion, such as liquid pumice. You can even find commercial products designed specifically for this task.

But chances are, if you've tried one or two of these to no avail, the scratches might just be too stubborn or deep.

Don't lose hope just yet. There are other routes you can try. Let's have a look at them.

Other options

Clear nail polish

For a different approach, you can rummage around your house for some clear nail polish. Any transparent polish will do.

The previous methods work by smoothing out the scratches. However, with nail polish, you'll be filling in the scratches.

Simply clean the glass well and apply a small layer of polish. It will take a little while to set.

After about an hour, use nail polish remover and a microfibre cloth to remove any excess polish. With a little luck, the scratch should be gone.

Sanding

This is where things get a little more serious.

Before you bring out the power tools, ask yourself whether you're confident using them. There's no shame in leaving it to a professional – and getting it wrong could do more damage than good.

Feeling up to it? You'll need an orbital sander or buffer and a buffing compound.

Now, start polishing the glass with the buffing wheel, adding small amounts of the buffing compound as you go. The idea is to make sure it doesn't dry out while you're working, as that could damage the glass.

After a while, clean the area with some water and inspect. As with all the other methods, you can rinse and repeat as needed.

When is it best to call a pro?

Maybe the scratches are just too severe, and our DIY aren't doing the trick. Or perhaps you're not ready to break out the power tools.

If that's the case, you might want to enlist the help of a professional window repair firm. Its experts can assess the state of your window and suggest the best way forward.

Naturally, this will be more expensive than a DIY solution. It's up to you whether the benefit justifies the cost. In some cases, it might be best to replace the window altogether.

When should I consider replacing the window?

A very scratched window is probably a very old window. Chances are, the scratches aren't the only problem with it.

That's where a replacement window can start looking like the most cost-effective option. Not only will the new window be scratch-free, but it will also come with many other benefits.

Modern options, such as our triple-glazed windows , outperform older windows in every way. Replace an old, worn window with triple glazing and you can expect:

Improved thermal efficiency , which can mean lower heating bills
Noise reduction – a perk if you live on a busy road
Less condensation
Better security

This way, a window replacement isn't just a visual improvement. It also brings financial benefits and improves the comfort level of your home.

So, will you tackle those scratches with some elbow grease, or do you think it's time for a replacement? We hope that our tips help you make an informed decision.

Which conservatory roof is best? (Glass vs tiled vs polycarbonate)

Mon, 02 Mar 2026 23:57:18 GMT

Let's compare glass, tiled, and polycarbonate conservatory roofs. What are the pros and cons of these 3 popular roofing systems?

When it comes to choosing a conservatory, most people focus on the doors, the frames, or how the room will look from the garden. But it's the roof that truly determines how the space feels to live in.

Too hot in summer. Too cold in winter. Deafening in heavy rain. Glare at certain times of day. These are some common issues that arise with conservatories – and they're almost always related to the roof. In other words, it's important!

So, what kind of roof is best? Glass, tiled or polycarbonate?

The honest answer is that each system has its place. The better answer is that it really depends on how you want to use the space. To help you make an informed decision, let's break down the pros and cons of all three.

Polycarbonate roofs

The pros

Polycarbonate was once the standard choice for conservatories across the UK.

These roofs are lightweight and easy to install. But most of all, they're cost-effective.

As it's usually the most budget-friendly option, polycarbonate is an attractive choice for homeowners who want to add space without a huge investment.

And because it's lightweight, it can often be fitted onto existing conservatory frames without major structural changes. Installation is usually quick and straightforward.

Modern polycarbonate sheets also offer improved UV protection compared to older versions.

The cons

Polycarbonate roofs aren't without their limitations.

They tend to provide less insulation than glass or tiled systems. This can lead to a space that becomes very warm in summer and noticeably cold in winter. As energy efficiency expectations have improved, this has become more of a concern for homeowners.

Noise can also be an issue. Heavy rain or hail can be loud – not always ideal if you want to use the space for work or relaxation.

Over time, polycarbonate can also discolour or lose clarity, affecting the appearance of the conservatory.

For occasional use, such as a bright garden room for the summer months, polycarbonate can still work really well. But for year-round living, many homeowners now look for something more substantial.

Glass roofs

The pros

Glass roofs are a popular modern upgrade and are often seen as the middle ground between polycarbonate and tiled systems.

Glass provides a sleek, contemporary finish. It allows plenty of natural light into the space, which is one of the key reasons people choose a conservatory in the first place.

High-performance glazing has improved significantly in recent years. Many glass conservatory roofs now include solar-control coatings and improved thermal insulation compared to older designs.

They also tend to be quieter than polycarbonate during heavy rain.

Visually, glass roofs maintain that classic conservatory feel, helping the space feel bright, airy and connected to the outdoors.

The cons

Even with modern glazing, glass roofs can still struggle with temperature extremes compared to a fully insulated tiled system.

Large expanses of glass can allow significant heat gain in summer, so blinds may be needed to reduce glare. And in the winter, heat loss can still occur through the glazed panels, even with improved insulation.

There's also the practical reality of cleaning. Glass roofs tend to show dirt a little more easily and may require extra maintenance to keep them looking their best.

While it may not be the ultimate choice for everyone, glass is still an excellent option if you want maximum light and that traditional conservatory aesthetic.

Tiled roofs (warm-roof systems)

The pros

Tiled (warm-roof) conservatory systems are designed to transform a conservatory into something much closer to a true extension.

Rather than relying on glazed panels, a tiled roof is fully insulated and finished with lightweight roofing tiles to match your home.

The biggest benefit of a tiled roof is its thermal performance. A properly designed tiled conservatory roof significantly improves insulation, helping keep the room cooler in summer and warmer in winter. This makes the space inviting all year round, not just on mild spring days.

Because the roof is insulated, noise is dramatically reduced compared to glass or polycarbonate. Heavy rain becomes a soothing background sound rather than a distraction.

A warm roof also changes how the room feels internally. With a plastered ceiling and the option for integrated lighting, the space becomes more like a natural continuation of your home rather than a separate garden structure.

Externally, tiled roofs can be colour-matched to your property, creating a cohesive, high-quality finish and a space that looks the part inside and out.

At Calder Windows, we specialise in SupaLite and Equinox tiled roofs – and we believe there are no better options on the market. Built to look great and last for decades, these thermally efficient conservatory roofs can really take things to the next level.

The cons

Tiled roofs are generally a larger investment than polycarbonate and sometimes more than glass. They are also heavier, which means structural suitability must be assessed properly.

However, modern warm roof systems are specifically engineered to be lightweight and suitable for many existing conservatories – provided they are installed by experienced professionals. (That's where we come in!)

Making the right choice for your home

The best conservatory roof isn't just about the materials – it's about what works best for your lifestyle.

If you love the bright, traditional conservatory look and want maximum natural light, a high-performance glass roof can be an excellent choice.

But if your goal is to create an energy-efficient space that feels as comfortable in January as it does in July, a tiled warm roof is often the superior solution.

At Calder Windows, we offer a range of conservatory roof options, including high-performance glass and advanced tiled warm roof systems. That means instead of compromising, you can choose the solution that truly fits your home and how you want to live in it.

If you're unsure which direction is right, why not talk to our team ? We can help clarify what's structurally possible and what will deliver the comfort you're looking for.

In the end, the best conservatory roof is the one that turns your conservatory into a space you love – all year round.

10 mood-enhancing lighting ideas for conservatories

Mon, 23 Feb 2026 22:29:15 GMT

Does your conservatory need a glow-up? Lighting is key. Discover 10 creative options that set a marvellous mood.

Picture a conservatory. Now, picture yourself inside the conservatory. What sort of scene have you conjured up?

If we can take a guess, we'd say you were relaxing on a comfy wicker sofa, basking in the sun's rays. Or pottering around, watering some plants under the warm glow of the morning sky.

In any case, you probably pictured a daytime scene. Conservatories are made of glass, after all, because they're designed to make the most of sunlight – right?

Yes. But just as a dog isn't just for Christmas, a conservatory isn't just for the daytime. With some judicious lighting choices, you can set a mood and make it just as pleasant a place to be come evening, too.

Don't know where to start? We've got you covered. Here are 10 creative ways your conservatory lighting can enhance the mood.

1. Layer up

Layering is a key principle of lighting in interior design. It involves combining different types of light to create a warm and welcoming atmosphere.

In layering, there are three main types of light: ambient, task and accent. Ambient light is the general lighting, whether from a ceiling fixture or natural light through the windows.

Task lighting is more focused and involves providing light for specific activities: a reading lamp on a desk, say, or vanity lights by a bathroom mirror.

Finally, there are accent lights. These highlight features in a room.

In the case of a conservatory, these three types of lighting can be combined to create a cosy atmosphere. To take just one set-up as an example: a wall light can provide ambience, a floor lamp can provide light for reading and uplights can provide highlights for your plants.

At the end of the day, layering enables you to adjust the lighting to suit different activities, moods and times of day. Exactly how you achieve this is up to you – and the possibilities are near-endless.

2. Get rid of glare

Glass is an essential feature of conservatories. But it can create a problem: glare. And if you're heading to the conservatory for downtime, you don't want eyestrain to ruin the vibe.

The best way around this problem is to install indirect lighting. This could involve uplights, downlights or hidden fixtures. Essentially, you want the light to bounce off ceilings and walls rather than the glass itself.

This doesn't just preserve your eyesight. It also means you can enjoy your view of the night sky without reflective glare. Win-win!

3. Get your garden involved

Entertaining or relaxing in your conservatory after dark? Then you might want to take steps to ensure the view from the conservatory is preserved during the evening hours.

You can easily achieve this by installing lights in your garden or patio. That will make sure your garden is visible in all its glory – much preferable to an inky black void.

This is a topic as extensive as conservatory lighting. Done well, it can make a significant positive difference to the mood in your conservatory.

4. Light your plants

For many, a conservatory is a home for plants. So, why not highlight your favourite specimens with LED spotlights, targeted floor lamps or specialist grow lights? This can enhance your plants as well as the mood.

5. Think smart

Smart lights are a relatively recent innovation – and they can make a huge difference to the mood of your conservatory.

This is primarily because you can set your smart lights to "scenarios". This means you can activate a specific lighting set-up with a simple voice command: "relaxation mode", say, or "dinner time".

Smart lights can also help if you're concerned about the security of your conservatory. Set your system to simulate occupancy and opportunistic thieves may look elsewhere.

6. Install indirect LED strips

An easy way to get cosy lighting in your conservatory is to strategically install LED strips. These can be placed behind pieces of furniture, along exposed beams or in the doorway.

And if you're really feeling adventurous, why not make these LED strips smart? This lets you adjust the brightness level and colour tone to suit your every whim with a simple voice command or touch of a button.

7. Explore natural materials

It's not just the light itself that enhances – or diminishes – the mood of your conservatory. It's also the materials the fixtures are made from.

If you want your conservatory to have a natural aesthetic, it's well worth exploring natural-looking materials such as rattan, bamboo and wood. You might be surprised at the difference this can make.

8. Light the space from floor to ceiling

The location of your lights makes as big a difference as their hue. Floor lamps create ambient zones for reading, gardening or dining, while pendant lamps and chandeliers do a similar job from above.

Where structurally possible, you can also install dimmable recessed spotlights in the ceiling. This gives you glare-free ambient lighting that doesn't clutter up the floor or walls.

Worried about powering your lamps? If you don't have sockets to spare, explore portable, rechargeable options – or install an extension lead so it hugs the wall.

9. Get cosy with fairy lights

Want your conservatory to look like a cosy grotto? This magical effect is a doddle to achieve. Simply drape LED fairy lights or string lights around beams and plants for a touch of enchantment.

10. Mount lights on the walls

Sometimes, ceiling fixtures are a logistical step too far. In this scenario, uplights and downlights can be mounted on the wall. These provide atmospheric lighting without any pesky glare.

How sash windows work: parts, anatomy and how it all fits together

Mon, 16 Feb 2026 23:16:37 GMT

Learn how sash windows work, explore their anatomy and components, and discover why they remain a popular choice for homes.

If you know your architecture, sash windows are instantly recognisable. Tall, elegant and effortlessly classic, they're a defining feature of many British homes. You'll see them on everything from Georgian townhouses and Victorian terraces to modern properties designed with heritage style in mind.

And behind that classic design is a surprisingly clever bit of engineering. If you've ever wondered what actually makes a sash window move, stay open and keep the weather out, you're not alone.

Let's take a closer look at how sash windows work, the key parts involved and what sets them apart from other window styles.

First things first – what exactly is a sash window?

A sash window is made up of one or more movable panels (sashes) that slide vertically – or occasionally horizontally – within a frame. Traditionally, sash windows are vertically sliding, with two sashes that move independently of one another.

This simple design allows for excellent ventilation, controlled airflow and a timeless appearance that has stood the test of centuries. While older sash windows relied on cords and counterweights, modern versions often use advanced balances and materials that improve efficiency and ease of use.

The anatomy of a sash window

At first glance, a sash window looks quite minimal. In reality, it's made up of several carefully designed components. These all work together to keep everything moving smoothly.

The frame

This is the outer structure that holds the entire window in place. It's fixed into the wall opening and provides the track within which the sashes slide.

The main parts of the frame include:

The jambs (the vertical sides)
The head (the top)
The sill (the bottom)

In modern uPVC sash windows, the frame is engineered to provide strength, weather resistance and insulation without the maintenance demands of timber.

The sashes

These are the moving parts that give the window its name. In a traditional vertical sash window, there are two sashes: the top sash, which slides downwards, and the bottom sash, which slides upwards.

Each sash is essentially a glazed panel held within its own frame. Together, they allow you to control ventilation by opening the top, the bottom, or both at once.

The astragal bars

These are installed on the glass to give the window the appearance of smaller panes, either structurally or visually. In period-style sash windows, they are a key part of achieving that classic look.

In modern uPVC sash windows, this feature maintains heritage charm while using larger, energy-efficient glass units behind the scenes.

The meeting rail

This is where the two sashes meet in the middle when the window is closed. It plays an important role in security and weatherproofing, helping to form a tight seal between the upper and lower sash.

Locks are usually fitted here, keeping both sashes securely closed when not in use.

How sash windows open and close

This is where things get really clever.

In old-fashioned sash windows, each sash is connected to a hidden counterweight via a cord or chain. This runs over a pulley at the top of the frame. The weight perfectly balances the sash, allowing it to stay open at any height.

While effective, this system requires space within the frame and regular maintenance over time.

Most contemporary uPVC sash windows, including ours, use something called "spring balances" instead of cords and weights.

These balances are concealed within the frame and use calibrated tension to support the sash. The result is smooth, effortless operation and no visible cords, with the added benefits of reduced maintenance, slimmer frames and improved insulation.

It's a modern solution that preserves the look of a traditional sash window without the drawbacks.

Ventilation: why sash windows are so effective

One of the biggest advantages of sash windows is how well they manage airflow.

By opening both the top and bottom sash slightly, warm air can escape from the top while cooler air enters from below. This natural convection system helps regulate indoor temperatures and improve air quality without creating strong draughts.

It's a design feature that was centuries ahead of its time and still works beautifully today.

How sash windows differ from casement windows

Casement windows are hinged and open outward, usually using a handle. While practical, they operate very differently from sash windows.

Sash windows slide vertically and don't protrude outwards – ideal for pavements or tight spaces. They offer controlled, balanced ventilation and suit period and heritage-style properties.

Casement windows open on hinges and can be more exposed to the elements. They often have a more modern appearance.

Neither one is better than the other in all cases. It's about choosing the right window for the style of your home and, of course, your own personal preferences.

Security features in modern sash windows

Older sash windows sometimes get an unfair reputation for poor security. Modern designs couldn't be more different.

Today, uPVC sash windows include multi-point locking systems, reinforced frames, toughened or laminated glass, and secure meeting rail locks.

These upgrades make modern sash windows highly secure, without compromising their elegant appearance.

Why uPVC sash windows are so popular today

Traditional timber sash windows are beautiful, but they require regular painting and upkeep. uPVC sash windows offer a practical alternative that still looks the part.

Key benefits include their excellent thermal efficiency, low maintenance (no need for sanding or repainting!), long lifespan, and their authentic period styling options.

For homeowners looking to retain character while improving comfort and efficiency, uPVC sash windows could be the ideal solution.

Bringing it all together

Every part of the sash window has a purpose. From the frame and sashes to the balances and rails, each element works together to create a window that's practical, beautiful and built to last.

Are you restoring a period property or adding a bit of classic character to a newer home? Understanding how sash windows work should make it easier to choose the right option for you.

Sometimes, the smartest designs are the ones that have been around longest!

Should I choose bifold doors or French doors?

Mon, 09 Feb 2026 23:13:46 GMT

Choosing between bifold doors and French doors can make a big difference to your property. Explore key considerations in our guide.

A house is like an outfit. Every element contributes to the overall vibe, from the smallest splash of colour to the most noticeable shapes and lines.

This is one reason why many homeowners agonise over interior design. The possibilities for personal expression are endless – and a little overwhelming.

Thankfully, no one has to design every feature from scratch. When it comes to large items of furniture and essential features like doors and windows, many people choose from familiar, readymade designs.

Take the case of floor-to-ceiling windows. Most homeowners choose between some kind of fixed picture window and some kind of large glass door. These doors fall into three main categories: bifold doors, French doors and sliding doors.

Even if you're unfamiliar with this terminology, chances are you can differentiate between these three classic types of doors. At its simplest, the difference lies in the way they open. Bifold doors open like a concertina, whereas French doors are split into two doors. Sliding doors, meanwhile, slide open along a rail.

It may be that one of these kinds of doors takes your fancy straight away. But if you're still unsure, there are other things to keep in mind: the cost, for one, and the access you need between the inside and outside of your property.

In this guide, we look at the differences between French doors and bi-fold doors, specifically. But before we explore the ins and outs of getting in and out, let's dive into the differences between these two stalwarts of interior design.

What are bifold doors?

A bifold door is similar to an accordion. It's made up of multiple framed glass sections connected by hinges. These fold up when closed and fold out when opened, sliding along a track.

Like any glass partition, bifold doors both separate and connect two spaces. Whether installed between indoor and outdoor areas or between large rooms, they provide a protective thermal barrier while simultaneously maximising the view.

They're often installed on patios and conservatories. They're also used to give homes a spacious, light-filled open-plan feel.

What are French doors?

Like bifold doors, French doors connect and separate indoor and outdoor spaces and provide a wide, unobstructed opening that lets plenty of light enter. The difference lies in the design.

Whereas bifold doors concertina open, French doors consist of a pair of double doors. These open from the middle. Some open inwards, some outwards and some both ways. Most of the time, these doors are covered in large glass panels with minimalist frames.

French doors are often an alternative to sliding patio doors. But why should you choose a set of French doors over their bifolding counterparts, and vice versa?

When should I choose bifold doors?

The main reason to get bifold doors is to create a large, airy space in your home. If your garden is something special, bifold doors can provide a large unbroken view.

In colder weather, bifold doors let you enjoy the chilly vistas without getting chilly yourself. And in spring and summer, you can seamlessly move in and out, bridging the gap between indoors and outdoors.

But bifold doors aren't only installed on external walls. They can also replace internal walls. If you want to combine an open-plan design with separate rooms, bifold doors are the way to go.

Then there's the question of aesthetics. Bifold doors have a sleek, contemporary look with minimalistic frames. This contrasts with the more traditional style that French doors offer.

Finally, there's the fact that bifold doors save on space. The folded panels stack neatly to the side, getting out of your way. If space is an issue, you may find these a better choice than French doors, which can swing inwards and cramp your style.

When should I choose French doors?

French doors share most of the benefits of bifold doors. So, why choose them for your home?

In our view, there are four main reasons:

French doors have a more traditional look than bifold doors. This can make them the ideal choice for older homes – or newer homes crying out for a little vintage flair.
French doors can be more appropriate for smaller spaces. If you want to replace an entire wall, both bifold doors and French doors can do the job nicely. But if you're working with standard door sizes, French doors are the ones to choose.
French doors are typically cheaper to buy and install than bifold doors, thanks to their simpler construction.
French doors are great for everyday use, operated by a simple turn of the handle. If you're regularly in and out of the garden or moving between rooms, they provide a user-friendly solution.

Why are they called "French" doors?

French doors have their origins in Italy – so why do we still call them "French"?

The answer is that this classic design took off in 17th-century France. They were designed to allow more natural light into the homes of nobles. Their combination of functionality and aesthetics soon impressed the rich in other countries, and French doors became an international sensation.

Today, French doors are like diamonds, lobsters and champagne. Once the preserve of the rich, they're now available to a much wider range of consumers.

What should you look for in a door installer?

A set of French doors or bifold doors is only as good as its installer. Work with the best and you'll have a solution that lasts. Go for second best and you'll soon be calling them back for repairs – or a costly replacement.

When shopping for these kinds of products, make sure you work with an experienced, reputable installer who can demonstrate the quality of their materials. You should also make sure your window-doors are fitted with modern multi-point locking systems for your peace of mind.

How uPVC windows are made

Mon, 26 Jan 2026 22:45:54 GMT

Discover how uPVC windows are made. We trace the whole process, from the raw materials to the precision-engineered frames.

Most of us don't give much thought to how our windows are made. We open them, close them, keep them clean, and simply trust that they'll do their job quietly for decades to come.

But behind every uPVC window is a carefully controlled process that balances chemistry, engineering, skilled craftsmanship and quality control.

From raw materials to the finished frame fitted in your home, uPVC windows go on quite a journey – and we're sharing that journey today. Because once you know a little more about how they are made, the importance of quality becomes clearer and clearer.

First, what does uPVC actually mean?

uPVC stands for "un-Plasticised Polyvinyl Chloride". (You can see why they shortened the name.)

In simple terms, this material is a rigid, durable form of plastic designed to withstand the elements without warping, rotting or corroding.

Unlike older plastics, uPVC doesn't contain the plasticisers that would give these materials their flexibility. This makes it ideal for windows and doors, where strength, stability and longevity are essential. It's also resistant to moisture, UV light and temperature changes, which is especially important in the unpredictable British climate.

uPVC itself begins life as a fine powder, blended with stabilisers, pigments and additives that enhance performance. These ingredients are carefully measured to ensure the final product meets strict standards for strength, colour retention and weather resistance.

Step 1: extrusion – shaping the window profiles

Once the uPVC compound is ready, it's time for extrusion. This is the process that gives window frames their recognisable shape.

The powder is heated until it melts into a thick, dough-like consistency. This is then forced through a precision-engineered metal die, which shapes it into long, hollow profiles. These profiles form the basis of window frames, sashes and mullions.

As the newly shaped uPVC emerges, it is rapidly cooled to lock in its form. The result is a strong, lightweight profile with internal chambers that improve insulation and structural stability.

These chambers are no accident. They're a careful part of the design, essential for trapping air, reducing heat loss and improving energy efficiency.

Step 2: reinforcing for strength and security

While uPVC is strong on its own, most window profiles are reinforced internally with galvanised steel or aluminium.

These reinforcements sit inside the hollow chambers and enhance rigidity, ensuring the frame won't twist or bow over time. This is especially important for larger windows and doors, where long-term structural integrity is key.

Reinforcement also plays a vital role in security. A solid internal structure provides a strong base for locks, hinges and hardware, helping your windows stand up to daily use (and any unwanted attention…)

Step 3: cutting, welding and shaping

Once the profiles are extruded and reinforced, they're cut to precise lengths based on the exact window specifications. Accuracy matters here. Even just a millimetre can affect how well a window fits, opens and seals.

The cut sections are then welded together at the corners using heat and pressure. This creates strong, seamless joints that are far more durable than mechanical fixings alone.

After welding, excess material is cleaned away to produce smooth, neat corners. This stage is part of what gives high-quality uPVC windows their clean, finished appearance.

Step 4: glazing and seals

With the frame assembled, attention now turns to the glass.

Modern uPVC windows use double or triple glazing, with sealed units designed to improve thermal performance and reduce noise. The glass itself is manufactured separately, then fitted into the frame using high-performance gaskets and seals.

These seals play a crucial role. They keep water and draughts out, help maintain consistent indoor temperatures and ensure the window operates smoothly for years to come.

Good sealing is one of the biggest differences between a window that performs well long-term and one that starts to fail prematurely.

Step 5: hardware and finishing touches

Locks, handles, hinges and ventilation components are fitted next. These elements are more than just decorative. They're essential to safety, usability and compliance with building regulations.

Quality manufacturers choose hardware that complements the strength of the frame, offering smooth operation and reliable security. At this stage, windows may also receive additional finishes, such as woodgrain effects or bespoke colour foils, depending on the design.

These finishes should be bonded to the uPVC surface during manufacturing, not painted on afterwards. This ensures they won't peel or fade easily.

Step 6: quality control and testing

Before a uPVC window is ready for installation, it goes through rigorous quality checks.

Frames are inspected for accuracy, weld strength and finish quality. Glazing units are checked for clarity and seal integrity. Moving parts are tested to ensure smooth operation.

Many manufacturers will also test windows for weather resistance, thermal performance and security standards. This final stage ensures that when a window leaves the factory, it's ready to perform reliably in real homes under real conditions.

Why manufacturing quality matters

On the surface, many uPVC windows look similar. But the way they're made – from the quality of materials to precision of assembly – makes a significant difference to how they perform over time.

High-quality uPVC windows are quieter, warmer, more secure and last much longer. They open and close smoothly, keep draughts out and retain their appearance year after year with minimal maintenance.

That's why choosing an experienced, reputable supplier matters just as much as choosing the window style itself.

From factory floor to family home

By the time a uPVC window is installed in your home, it has already been through an impressive transformation. It's gone from a raw powder to a precision-engineered product, designed to protect, insulate and enhance your living space.

That's why, at Calder Windows, we only source uPVC windows from a select few trusted suppliers. We want to know that the process is guided by experience, genuine care and an understanding that windows aren't just components. They're a key part of how a home feels, functions and lasts.

Cleaning soffits and fascias: how to do it and how often

Mon, 19 Jan 2026 21:20:24 GMT

Learn how to clean soffits and fascias properly, how often they need attention and when replacing them might be the easier option.

Soffits and fascias are the unsung heroes of your home exterior. They sit quietly beneath your roofline, keeping everything ventilated, protected and tidy. And for the most part, they ask very little in return.

Until one day, you look up.

Maybe you've noticed some unsightly green streaks after a wet winter. Perhaps some black spots have appeared that definitely weren't there before. Or maybe you suddenly realise you've lived in your house for over 10 years and have never once cleaned them. Yikes!

If any of that sounds familiar, don't worry – you're not alone. The good news is that cleaning soffits and fascias is simpler than most people expect. Plus, knowing how often to do it can save you a lot of effort in the long run.

OK, first things first – what are soffits and fascias, exactly?

Before we jump into cleaning tips, here's a quick refresher.

The fascias are the long, straight boards that run along the edge of your roof, supporting the bottom row of tiles and holding the guttering in place.

Soffits sit underneath the fascias, bridging the gap between the roof edge and the wall. They often contain ventilation to help prevent condensation and damp in your roof space.

Together, they protect your home from weather damage, pests and moisture. They also give your roofline a clean, finished appearance.

How often should you clean soffits and fascias?

For most homes, a light clean once or twice a year is more than enough.

A good rule of thumb is to associate the schedule with the changing of the clocks:

Once in the springtime: when the clocks go forward, it's time to wash away winter grime, moss spores and any built-up pollution.

Once again in the autumn: before the clocks go back, freshen them up again ahead of the darker, wetter months setting in.

If your home is near trees or busy roads, or exposed to prevailing weather, you may find that they need attention a little more often. But if they're modern, made of uPVC and generally well looked after, this is usually a quick job rather than a dreaded chore.

How to clean soffits and fascias safely

"Safely" is the operative word here. These areas are high up, and there's no prize for cleaning enthusiasm if it involves wobbling on a ladder with a full bucket in one hand.

Assuming you feel comfortable working at height, here are our instructions for the safest approach.

What you'll need

A sturdy ladder (with someone to hold it and keep a close eye on things from the ground if possible)
A bucket of warm water
Mild detergent or washing-up liquid
A soft sponge or cloth
A soft-bristle brush for stubborn marks
Optional: a hose for rinsing

The cleaning process

Start by gently brushing away loose dirt, cobwebs and debris. Next, wash the surface using warm, soapy water and a sponge or cloth. Work in sections, rinsing as you go to prevent streaks.

For more stubborn marks such as algae, traffic film or bird droppings, a soft brush can help. Avoid abrasive pads or harsh chemicals, which can scratch or dull the surface.

Once the area is clean, give everything a thorough rinse and allow it all to dry naturally.

What not to do

This part is just as important!

Do not use pressure washers directly on soffits and fascias. They can force water into places it shouldn't go.
Avoid cleaning detergents which are high in bleach. They can discolour uPVC and damage seals.
Do not ignore ventilation holes. These should be gently cleaned and not blocked.

Remember: a gentle, regular clean is far better than an aggressive blitz once every five to 10 years.

When cleaning stops being enough

Time for a bit of brutal honesty.

If your soffits and fascias are…

peeling
cracked
warped
rotting
constantly streaking, no matter how often you clean them

…then the issue might not be just dirt after all.

Older timber soffits and fascias require regular painting and maintenance. Over time, even the most diligent cleaning won't stop them from deteriorating.

This is usually the point where homeowners realise that the problem isn't cleanliness, but maintenance.

The low-maintenance alternative: modern uPVC soffits and fascias

Modern uPVC soffits and fascias are designed to:

Resist moisture and rot
Prevent peeling and flaking
Stay brighter for longer
Require only occasional cleaning
Never need painting

In real terms, that means a quick wash once or twice a year – and that's it!

No sanding. No repainting. No climbing ladders every other fortnight, wondering why you ever thought timber had charm.

They also improve ventilation, protect your roofline and instantly freshen the look of your home – and more than you might expect.

A practical decision, not just a cosmetic one

Replacing soffits and fascias isn't about appearance – though when they look good, it does make a noticeable difference.

Worn or damaged boards can allow moisture into your roof space, contribute to damp issues and even affect the performance of your guttering. Upgrading to modern materials helps protect your home structurally, not just visually.

This is one of those improvements you don't think about often, but once it's done, you wonder why you waited so long.

Clean what you can, replace what you should

If your soffits and fascias are in good condition, a regular gentle clean will keep them looking smart and doing their job quietly in the background.

If cleaning feels like fighting a losing battle, then it might be time to consider replacing them with something designed for modern life.

At Calder Windows, we help homeowners choose uPVC soffits and fascias that look great, last for years to come and free them from unnecessary maintenance. Because sometimes the easiest clean is the one you don't have to keep repeating.

We think that's a very satisfying kind of upgrade!

5 patio door window treatments for style and privacy

Tue, 13 Jan 2026 23:59:58 GMT

Discover the best patio door window treatments for privacy, warmth and style – from sleek blinds to soft curtains that elevate your space.

Patio doors are one of the best features a home can have. They flood rooms with light, blur the boundary between indoors and out, and make even small spaces feel bigger and brighter.

But with this attractive feature, a familiar dilemma often presents itself. How do you keep all that lovely light while still feeling comfortable, private and cosy?

The right window treatment can completely transform the look and feel of your patio doors. They can improve insulation, soften harsh sunlight or add a layer of style that ties the whole room together.

We've come up with five of the best patio door window treatments to get you inspired for an interior refresh. Whether your doors open onto a garden, a balcony or a busy street, you'll find them all practical, stylish and easy to live with.

1. Vertical blinds: practical, flexible and quietly reliable

Vertical blinds have long been a popular choice for patio doors, and for good reason.

These blinds are easy to operate. They slide neatly out of the way when doors are in use. And they give you excellent control over both light and privacy.

Tilt the slats and you'll let daylight in while still blocking direct views from outside. That makes them especially useful for overlooked gardens or rooms on the ground floor.

Modern vertical blinds have also moved a long way from their slightly corporate reputation. Today's designs include soft fabrics, textured finishes and warm neutral tones that suit living spaces beautifully.

Are they the best choice for you?

We recommend vertical blinds for homes that need flexible privacy control and a neat, no-fuss look.

2. Curtains: soft, cosy and endlessly versatile

Want to add warmth, softness and a touch of cosy chic to a room? Curtains can be styled in many different ways to suit your home.

Framing patio doors with floor-length curtains can make the space feel taller, more elegant and more inviting – especially in living rooms and dining areas. They're also an excellent way of adding insulation, helping to keep warmth in during winter and block out strong sunlight in summer.

For everyday practicality, many homeowners pair curtains with a discreet roller blind behind them. This gives you daytime privacy without the need to close the curtains completely, while still allowing for full coverage and extra warmth in the evenings.

Are they the best choice for you?

We recommend curtains for cosy living spaces, period homes or anyone wanting a softer, more decorative finish.

3. Roller blinds: sleek, minimal and thoroughly modern

If you prefer clean lines and simplicity, roller blinds are a brilliant option for patio doors.

They sit neatly within the frame or just above it, making them ideal for contemporary spaces where you don't want the window treatment to dominate the room. Available in everything from sheer fabrics to full blackout options, roller blinds can be tailored to suit exactly how much light you want to let in.

Light-filtering rollers are particularly popular for patio doors, as they maintain brightness while reducing glare and visibility from outside.

Are they the best choice for you?

We recommend roller blinds for modern interiors, kitchens and any space where a minimalist look is key.

4. Panel blinds: stylish and made for large openings

Panel blinds are a fantastic solution for wide patio doors and large glazed areas.

Rather than individual slats, panel blinds use wide fabric panels that slide smoothly along a track. This makes them easy to open and close, while also creating a bold, contemporary statement.

They work particularly well in open plan spaces, where their clean lines can echo architectural features and keep the room feeling uncluttered. When fully open, the panels stack neatly to one side, allowing uninterrupted access to the outdoors.

Are they the best choice for you?

We recommend panel blinds for larger patio doors and modern, open-plan layouts.

5. Venetian blinds: control light with precision

Venetian blinds offer one of the highest levels of control when it comes to light and privacy.

By adjusting the angle of the slats, you can let daylight bounce into the room while keeping direct views out. This makes them ideal for homes that need privacy without sacrificing good natural light.

Aluminium and wood options are particularly well-suited to patio doors, as they are durable and easy to clean.

While often associated with windows, Venetian blinds also work beautifully on patio doors when fitted thoughtfully and proportioned correctly.

Are they the best choice for you?

We recommend Venetian blinds for homes that want precise light control and a structured, contemporary feel.

Choosing the right option for your patio doors

When deciding on a window treatment, it's worth considering a few practical questions:

How often do you use the doors?
Do you need privacy during the day, evening or both?
Is insulation important in this room?
Do you want the treatment to stand out or blend in?

The best solution is usually the one that fits your daily habits, not just your décor preferences.

Even the most beautiful window treatment works best when paired with well-fitted, energy-efficient patio doors.

Modern uPVC patio doors offer excellent thermal performance and smooth operation. Plus, their slim sightlines maximise natural light, giving your blinds or curtains the perfect frame to work with.

At Calder Windows, we help homeowners think about the whole picture. With our help, your doors can do more than simply look great – they can also perform brilliantly and work seamlessly with your chosen window treatments.

Let the light in on your terms

Patio doors should make your home feel open, bright and welcoming without making you feel exposed.

With the right window treatment, you can enjoy the best of all worlds. You can get sunlight when you want it, privacy when you need it, and a space that feels finished and thoughtfully designed.

Prefer soft curtains? Sleek blinds? Something in between? In any case, choosing your window treatments well will elevate not just your patio doors, but the entire space around them.

Replacing a conservatory with an orangery: 5 key considerations

Mon, 05 Jan 2026 23:44:19 GMT

Thinking of replacing your conservatory? Discover the key differences, costs and benefits of upgrading to a stylish, energy-efficient orangery.

For many homeowners, a conservatory starts life as a dream space. An airy space filled with light. A bridge between the house and the garden.

But whether it's due to poor materials or inadequate installation, things don't always go to plan. Maybe the conservatory is too hot in summer and too cold in winter. Or perhaps it ends up being used for storage more often than for relaxation.

Don't give up just yet. If you've fallen out of love with your conservatory, you've got options.

You could upgrade your conservatory with a heat-conserving tiled roof . You could switch it for a modern, energy-efficient model. Or, if you're feeling adventurous, you could replace it with a sturdy, elegant orangery.

An orangery offers the same light and garden connection people love in their homes, but with the comfort and reliability of a brick-built extension.

Thinking about making the switch? Here are five things to think about before you get started.

1. Understanding the difference: conservatory vs orangery

Before diving into the planning stages, let's clarify what separates an orangery from a conservatory and find out if it's the right choice for you.

A conservatory is typically dominated by glass. We all know how they look – think glazed walls, glazed roof and minimal solid structure. This is what gives them that bright, airy feel. However, it can also be the reason some older conservatories struggle with temperature control.

By contrast, an orangery is more solid by design. It usually features brick or rendered walls, large windows or doors, and a partially solid roof with a central glazed roof lantern or skylight. That balance makes a huge difference to how the space performs.

To sum up:

A conservatory prioritises light
An orangery balances light and livability

Looking to implement a space that genuinely feels like a natural part of the home rather than an add-on? An orangery is often the more practical long-term choice.

2. Comfort and year-round use

One of the biggest motivations for replacing a conservatory is a simple one: comfort.

Old or low-quality conservatories can feel like a greenhouse in summer and a fridge in the winter. Even with blinds, heaters or fans, they sometimes end up being pleasant to use only for a few months of the year.

Orangeries are designed to solve this problem. With solid walls, insulated roofing sections and modern glazing, they retain heat effectively in winter while staying cooler in the warmer months.

That improved thermal performance means your orangery can be used and enjoyed all year round. Many homeowners use them as dining spaces, family rooms, home offices, or simply somewhere to relax without needing to adjust the thermostat first.

3. Planning permission and building regulations

One of the more practical considerations is paperwork.

In many cases, replacing a conservatory with an orangery can fall under permitted development, meaning planning permission isn't required. However, this can all depend on factors like size, height and proximity to boundaries.

Building regulations are more likely to apply to orangeries than conservatories, particularly because orangeries are classed as more permanent structures. This is no bad thing – it simply ensures the space meets standards for insulation, structural integrity and safety.

A good installer will follow building regulations to the letter. With planning permission, however, it's your responsibility to check whether it's required and make the proper enquiries. A little homework goes a long way.

4. Cost and long-term value

There's no getting around this part: upfront, an orangery does tend to cost a little more than a conservatory.

However, it's well worth looking at the bigger picture when considering your options for upgrading.

While the initial investment will likely be higher, orangeries can offer better long-term value. They're often more durable, more energy efficient and more likely to be used daily rather than seasonally. They can also enhance the overall appearance and layout of your home, both inside and out.

From a property perspective, an orangery can feel more like a "true" extension. Potential buyers may perceive it as a genuine expanded living space rather than an extra room they might be unsure what to do with.

Does your conservatory currently sit unused for half the year? Upgrading the space to an orangery can turn that wasted square footage into one of the most valuable rooms in your home.

5. Design, light and how the space will feel

One of the most common concerns when moving away from a conservatory is losing all that lovely light. But a well-designed orangery won't feel dark or closed in – quite the opposite, in fact.

Roof lanterns and glazed sections are designed to draw light deep into the space, while large windows and doors keep the garden feeling close by. The added structure also allows for features like atmospheric lighting, ceiling speakers and integrated heating – details that make the space feel intentional, warm and complete.

Design-wise, orangeries are very versatile. They can complement traditional homes with classic detailing or give them a contemporary lift, as well as suit modern properties with clean lines and minimal finishes. The key is designing the space to feel like a natural extension of your existing home, rather than a bolt-on.

So, is an orangery right for you?

Replacing a conservatory with an orangery is more than just a cosmetic upgrade – it's a real lifestyle glow-up.

Are you looking for a space that's comfortable all year round, visually cohesive with your home and genuinely enjoyable to use day to day? An orangery might be the better choice. It offers light without the glare, structure without heaviness and flexibility that adapts as your needs change.

As a trusted orangery supplier , we work closely with you to assess whether an orangery is the right solution. And with years of experience in supplying and constructing extensions, we design spaces that feel considered, comfortable and built to last.

So, if you're in Yorkshire and have a conservatory that no longer works the way you'd hoped, get in touch to discuss your options . Replacing it with an orangery could be the change that finally unlocks the full potential of your space.

4 extension ideas for semi-detached houses

Mon, 29 Dec 2025 10:29:09 GMT

Ready to level up your semi? Discover 4 ideas for extensions that maximise space and kerb appeal.

If you watch TV shows like Grand Designs , you'd be forgiven for thinking impressive extensions were only an option for the super-rich and super-rural.

But you don't need bottomless pockets or acres of land to enjoy the luxury of an extension. With some savvy planning, even a humble terraced house can gain a bit of space and a tonne of kerb appeal.

So, if you live in a semi-detached house, you're already off to a good start. You probably have more space than your average terraced dweller. And with roughly 30% of the English and Welsh population living in semi-detached housing, you're one among many. That means there are plenty of options designed just for homeowners like you.

Naturally, there are limitations (you can only gain so much space) and considerations (did someone say "planning permission"?) But if you get your ducks in a row and your paperwork filed, you could soon be enjoying a brand-spankingly spacious new room.

Let's start by looking at these important considerations. Then we'll share some smart extension ideas that might just suit your home.

Things to think about when planning a semi-detached extension

Permitted development rights

You can think of permitted development rights (PDRs) as pre-granted planning permission for certain projects. If your extension falls under your PDRs, you can go ahead and build it without seeking full planning permission.

Bear in mind that the rules can be complex, and they don't apply to all dwellings equally. Study the rules carefully so you know what you're getting yourself into. And consider applying for a Lawful Development Certificate, which confirms your project is above board with the council.

Restrictive covenants

Even if your extension falls under PDRs, you should still check for restrictive covenants on your property deed. These are special rules that stop you from doing certain things on or with the property.

Covenants can range from 'don't paint your house a certain colour' to 'don't build an extension – any extension'. Check carefully. You don't want to land yourself in hot water with the powers that be.

Planning permission

If PDRs don't apply, you'll need to seek full planning permission from your local authority. This could happen if your project

exceeds the limits of permitted development or
you live in a protected area, such as a National Park or conservation area.

Allow plenty of time to apply. For most small-scale extensions, you should get a decision within eight weeks.

Staying friendly with the neighbours

This is a big consideration for semi-detached dwellings. No amount of wishful thinking will change the fact that you've got neighbours next door – and they might have strong opinions about your plans.

There are several things to think about here:

Planning permission disputes: neighbours can (and do) raise disputes about planning permission. Be prepared to work towards a compromise.
Boundary disputes: building projects have a habit of stirring up old gripes about property boundaries – especially if the boundaries are unclear.
The Party Wall Act: this law says you must give your neighbour formal notice if you plan to work on a shared wall or property boundary.
Access for construction: if you need to move people or materials across your neighbour's land, you'll need to agree this with them in good time.

Building regulations

Explaining the ins and outs of UK building regulations would take a book, not a blog post. Just bear in mind that it's your responsibility to make sure they're adhered to.

Four semi-detached extension ideas to boost space and property value

1. Don't forget the classic conservatory

Conservatories are popular for a reason. As an estate agent might say, they bring the outdoors in. They're flooded with light, which is a big boon for sun-deprived British homes. And their popularity means there are plenty of tailor-made options for suburban semis.

And don't listen to the negative Nathans. Sure, old-style conservatories had issues with heat efficiency (roasting in summer, freezing in winter – you know the drill). However, a good, modern conservatory can be very efficient indeed. With double glazing and other eco-innovations included as standard, they're perfectly pleasant all year round.

2. Consider extending to the front

When planning an extension, it's tempting to put all your eggs in your back garden. After all, back gardens tend to be larger than front gardens, so that means more space to play with – right?

Sure – but as an osteopath once said, don't sleep on your front. Since you only share one boundary, you could find plenty of untapped potential in the unattached side at the front of your house.

Even a simple front porch extension could pay dividends. By creating a dedicated room for shoes, coats and keys, you free up space inside your home. That space could become a larger entrance hall or even add a few valuable feet to your living room.

3. Go extra-classy with an orangery

Even the name sounds special, doesn't it? "O-ruhn-juh-ree."

Well, these extensions are special. They're flanked with wall-to-ceiling glass, much like a conservatory. But they also feature more prominent brickwork and, some might argue, a more classically elegant design.

The result is an extension that's as bright and airy as a conservatory but as warm and cosy as any other room in your home. And we mean warm – orangeries tend to hold heat better than their all-glass cousins.

You might want to plump for an orangery if you want to use your extension as a dining room or regular living space.

4. Think upwards, not just sideways

While semi-detached homes usually offer more space to play with than terraced houses, your footprint only stretches so far. Plus, the further you extend outwards, the more you risk disputes with neighbours or ending up with a brick monstrosity in your garden.

That's why it can be helpful to consider building upwards, as well as sideways.

The classic upwards extension, of course, is the tried-and-true loft conversion. You've got space in your roof, so why not capitalise on it?

But don't sleep on multi-storey outdoor extensions, either. Not only do these double your available space, but they often end up cheaper per square metre.

Just be mindful of the 45-degree rule. Simply put, this means your extension has to fit within a 45-degree line drawn from your neighbour's nearest downstairs window. If you can tuck a two-storey extension within that space, you're golden.

Wooden windows vs uPVC windows: which is best for your home?

Mon, 15 Dec 2025 12:45:44 GMT

New windows come in all sorts of styles and materials. Let's compare wood and uPVC windows and explore their pros and cons.

What are windows for? This isn't the start of a riddle, poem or cracker joke. It's a question that plays a big part in the window you choose for your home.

Well, windows keep out the cold and let cool air in – sure. But they also contribute to your home's thermal efficiency and make an aesthetic statement.

These three things are of greater or lesser importance to different people. How important they are to you will be a factor when you come to choose the materials for your window frames.

In the world of window frames, one debate rages: wood or uPVC? Traditionalists swear by wood while pragmatists say uPVC does the job just as well, if not better.

So, which one is right for you? In our view, there are five things to take into consideration:

Cost
Maintenance
Energy efficiency
Longevity
Aesthetics

There's also the question of the kind of property you live in. Period properties, for instance, can lose value if fitted with uPVC windows.

But the simple answer is this: if you want a traditional look and don't mind extra upkeep, go for wood. If you want a high-performing window that looks good but not quite antique, uPVC is the way to go.

Want to know more? Let's break down those five factors to guide you on your buying journey.

1. Cost

Wooden windows are more expensive than uPVC – at least 50% more, in fact.

For some, this is well worth the expense. If authenticity is a priority, that's a few hundred extra quid well spent. But for some, the added maintenance that wood requires makes it a no-go.

That's not the end of the story, however. This is simply a comparison of the initial cost. You also need to consider how long the window lasts. The fact that wood lasts longer than uPVC makes it a valuable investment for some.

At the end of the day, your budget is probably the key factor in deciding between wood and uPVC. If you've got the money to spend, you may choose to go with wood. If you're looking for cost-effectiveness, however, uPVC satisfies most.

2. Maintenance

How much effort are you willing to put into the upkeep of your windows? Think carefully before you commit to wood or uPVC frames.

uPVC is easy to clean – really easy. A regular wipe with warm, soapy water and a soft sponge or cloth and your windows will sparkle like the day they were fitted.

Wood frames are cleaned in the same way. But unlike uPVC, they're prone to weather damage. That means regular repainting and sealant checks.

This isn't just a question of aesthetics. When wood deteriorates, gaps form. This can cause a range of problems, from draughts to pest damage.

If you're willing to put the work in – or pay someone to do it for you – then wood is worth it. For those who want an easy life, however, uPVC is as simple to deal with as ABC.

3. Energy efficiency

We're living at a time when energy efficiency is growing in importance for your average Joes and Joannes. Whether it's to cut carbon emissions, energy bills or both, many homeowners want to choose the energy-efficient option.

So, which is it? If you consider the frame alone, well-kept wood is a better insulator than uPVC.

But a window isn't just a frame. If you fit a uPVC frame with toughened glass, the complete unit will be just as energy-efficient as a wooden framed equivalent.

Oh, and if you get a toughened glass pane, you'll also have a window that's harder to break – and when it does break, it will break into lots of small, smooth pieces rather than dangerous shards.

The differences aren't substantial. For this reason, many homeowners are satisfied with uPVC. If you choose wood, it's likely to be for another reason.

4. Longevity

The lifespan of your windows matters. uPVC lasts around 35 years, whereas wood, when well-maintained, can last 60 or more.

How much this matters to you will depend on your plans for your home. Are you hoping to live there for decades? Will it be inherited by your children? Are you hoping to sell?

Whatever the answers to these questions, it's worth considering the kind of durability you require before purchasing a new window. Otherwise, you may find yourself frustratedly replacing uPVC frames – or, conversely, wondering why you spent so much on wood frames in the first place.

5. Aesthetics

For many buyers, this is the most important factor. Do you want an authentically traditional window? Then wood is the obvious choice.

If not, uPVC does the same for less. It comes in a wide range of colours and finishes and suits both classic-looking and modern-looking properties.

It's worth saying, however, that the visual difference between wood and uPVC is increasingly hard to spot. Connoisseurs will spot uPVC a mile off – but for the rest of us, a uPVC window with a wood effect does the job just as well.

How to child-proof windows

Mon, 08 Dec 2025 23:48:13 GMT

Windows can be a hazard for young children if not properly secured. Discover tips and products that can help keep your kids safe.

We know what it's like. You become a parent, and suddenly every household fixture becomes a potential hazard.

Plug sockets? Yep, hazard – better put covers on those. Stairs? Of course – a stair gate is a must. Windows? In some cases, yes – if you don't take the right precautions.

We don't want to worry you when you already have 5,000 things to fret about. But the statistics are pulse-quickeningly stark. According to the Child Accident Prevention Trust, one child under 10 is admitted to hospital daily after falling from a building.

The good news is that these accidents can almost always be avoided. It might just mean a bit of forward planning. Or it could mean investing in safety devices or even a whole new window. But we think you'll agree – that's a small price to pay for your child's safety and your peace of mind.

In this guide, we talk you through the basics of child-proofing windows – the risks, the solutions and when an upgrade is the safest option.

What dangers do windows pose for children?

Kids are a curious bunch. To them, a windowsill is an invitation to practice their climbing skills and see what's going on in the big, wide world outside.

That's why windows pose a particular risk to pre-school children. They often learn to climb before they learn to walk. And even a fall from a ground-floor window is a nasty fall when you're three-foot-nothing.

But falling out of windows is just one potential hazard. Kids who clamber also risk falling indoors – from the windowsill onto the hard floor below.

Finally, there's the risk of unsavoury types gaining access to your home. Vigilance and good home security are your friends here. With windows, that means high-quality, multi-point locking systems and modern double or triple glazing .

Five simple steps you can take

1. Keep low furniture away from windows

By "low furniture", we mean anything kids could climb to reach the windowsill. Remember: falls from windowsills are as much of a risk as falling out of the window. Your best defence is to keep your children off the windowsill altogether.

2. Keep windows locked (but know where to find the key)

If you're not using a window, keep it securely closed and locked. This helps reduce the risk of kids falling out, as well as intruders getting in.

That said, you should never lock a window without knowing where to find the key. In an emergency, you might need to use that window as an escape route.

3. Keep kids away from open windows

You can't keep windows closed all the time – but you can do your best to keep your kids away from the danger. If you need to open a window for ventilation, make sure your little adventurers can't access the room.

4. If possible, open windows from the top

Some types of windows offer safer opening options. With double-hung sash windows , for instance, you can slide the top pane to create a narrow ventilation slot. And with tilt-and-turn windows , you can choose to open them from the top rather than the side.

If your windows allow it, do it. An opening at the top is much harder for children to access than one at the bottom or side.

5. Educate your children on the dangers

As soon as your kids are old enough to understand, explain the risks in child-friendly terms. It might not stop them from exploring, but it should give them pause before their next daredevil climb.

Window child-proofing equipment

If you want to be extra-safe, you could consider investing in special child-proofing equipment. These gadgets are designed to allow for ventilation while preventing falls.

Window restrictors

Window restrictors fit inside the window frame and use a simple hook mechanism to stop the window from opening fully. Typically, they allow for an opening of about 10cm – wide enough to ventilate the room, but narrow enough to prevent access to the outside.

If you have modern windows, they may already be fitted with window restrictors. If not, you can retrofit them to most existing frames.

Window guards

Window guards are like stair gates for windows. They cover the entire width of the window with metal bars, providing a robust barrier against falls.

Window guards come in all shapes and sizes. Some cover only half the window's height and can swing open when a child-proof lock is disengaged. Others cover the window entirely but can be retracted so you can open the window and ventilate the room. Prices range from around £50 to £400 or more.

Tilt-and-turn windows

Tilt-and-turn windows are a modern marvel. Thanks to some clever German engineering, they can open in one of two directions – from the side, like a door, or inwards from the top. When opened from the top, they create a ventilation slot that's too narrow and too high for kids to access.

Naturally, replacing your windows is a big investment. But depending on your tolerance for risk, it may well be worth it – especially if your windows are too old or worn to be safe.

When should you replace a window to keep kids safe?

It always pays to be vigilant where kids and windows are concerned. But it's worth remembering that not all windows are created equal.

Modern windows are, generally speaking, much safer than older windows. All new windows come with double or triple glazing , which is much harder to break into or out of. They include multi-point locking systems for better security. And they're often fitted with window restrictors as standard.

Plus, with innovations like tilt-and-turn windows , you can ensure safety without having to put up with a muggy, damp, unventilated home.

With that in mind, your safest bet might be to replace the window entirely. You should seriously consider this option if:

Your window has no locks or inadequate locks: a simple catch mechanism won't do. You need sturdy, modern locks that only adults can operate.

Your window locks are broken: broken locks are as bad as no locks at all. And while you could replace the locks, the fact that they're worn and broken might signal it's time for an upgrade.

You have single-glazed windows: not only are single-glazed windows insecure, but they're also highly inefficient. Upgrading will help keep your children safe and work wonders for your energy bills.

Tips for buying uPVC doors online

Mon, 01 Dec 2025 23:54:29 GMT

Buying uPVC doors online doesn't have to be a guessing game. Keep these tips in mind and you'll all but guarantee a good deal.

A new door. It's not a purchase many of us plan for.

Loft conversions, extensions and conservatories , sure. Those are the kinds of investments that require real thought and real planning. But a door is just a door, right?

Not so fast. Doors are important – and if you rush into a purchase without proper forethought, you risk swapping a front door for a front dud.

Your door is the first thing people see when they enter your home, so it needs to look the part. It's one of your primary defences against burglars, so it's got to be strong and secure. And it's going to spend a long time outdoors in the Great British Weather, so it needs to be long-lasting and require minimal maintenance.

Thankfully, high-quality uPVC doors tick all the boxes – and they're readily available online from suppliers like Calder Windows.

But doors aren't books or smartphones. You can't click 'Add to basket' and know you're getting something first-rate at first glance. How can you know your door will be up to scratch when you're ordering it sight unseen?

We've got you covered. Here's our guide to ordering uPVC doors online – and making sure you get what you pay for.

Why choose uPVC doors, anyway?

Not sure which type of door is best for you?

At Calder Windows, we supply and fit a wide range of doors – from strong-and-sturdy composite doors to timelessly elegant heritage-style doors . All have their perks. But if you asked us to name the best all-rounder in the world of doors, we'd plump for uPVC in a heartbeat.

Yes – for most people, most of the time, uPVC doors will do the job and do it well. Here's why:

They're durable: uPVC is a type of plastic that's strong and firm by design. You can expect a uPVC door to last upwards of 20 years – even in the harsh British weather.
They're low-maintenance: forget varnishing, painting and other nagging maintenance tasks. uPVC doors never rot and only need an occasional wipe with warm, soapy water.
They're secure: buy a high-quality uPVC door and you'll have one more reason to sleep easy. At Calder, our uPVC doors come with Yale eurocylinder locks rated to the UK's highest security standard.
They're energy-efficient: once upon a time, doors were draughty, inefficient things. But modern uPVC doors effectively trap heat, meaning a warmer home and lower energy bills.
They look good: uPVC doors are available in a vast range of styles and colours, so it's easy to choose the right look for your home and your taste.
They're affordable: it's as simple as that. uPVC doors are almost always cheaper than their composite counterparts. Ka-ching!

Tips for buying uPVC doors online

Make doubly sure you're happy with the design

Ordering online is convenient for everyone, but it does come with a few downsides.

With doors, one of the biggest drawbacks is that it's hard to get a good feel for, well… the look and feel.

Back in the day, you'd visit a door showroom and peruse dozens of styles. You'd see the door from all angles. You could touch the door and get a feel for its strength. By the time you were done, you'd really know the door you were planning to buy.

The good news is that this is still an option. Visit our showroom in Normanton, West Yorkshire, and you can see the quality of our doors for yourself. Plus, our friendly, knowledgeable team will be on hand to answer any questions.

But there's no pressure to buy on the day. You can go home, have a good old think and order online when you're ready.

Another option is to use our online door designer tool . This lets you play around with dozens of classic and contemporary styles until you find the design that's just right for you.

Look for markers of quality

We know it's not always convenient to visit a door showroom. Sometimes, your only option is to click buy and hope for the best.

Or is it? See, with a little shopping savvy, it's more than possible to make sure you get the door you bargained for.

The key is to look beyond the surface and dig into the details. Sure, most suppliers will claim their doors are "high-quality". But are they fitted with high-quality locks? What's their U value (energy-efficiency score)? Do they come with reinforced steel frames?

It's these finer details that will help you paint a fuller picture of the door's quality and value.

And don't forget to look at reviews. Door suppliers might sugarcoat things, but you can trust other customers to give you an honest appraisal of quality.

Scrutinise your supplier

Be wary of buying good doors from dodgy firms. Your choice of supplier is just as important as your choice of door.

There are a couple of reasons for that. The first is that the quality of workmanship matters. If your uPVC door is poorly fitted, you could end up with an insecure, inefficient result – even if the door itself is up to snuff.

Secondly, it's best to work with a trusted company because trusted companies provide good aftercare. If something does go wrong, you want your voice heard and your issues resolved – not to be left with a duff door and a headache.

Again, a bit of internet detective work can help. Keep an eye out for:

Good reviews: again, reviews are your friend here. Read customer testimonials and look for overall scores of 4.5 stars or more.
Aftercare promises: doors should last – and so should your aftercare. If a company offers lengthy warranties, you'll know you're in safe hands.
FENSA approval: FENSA is a government-authorised scheme that makes sure door and window suppliers stay compliant with building regulations. When you choose a FENSA-approved supplier, you can be sure it will fit the door to a high standard.
Knowledge and experience: there's no substitute for years of service. How long has the supplier been in the trade? And when you ask questions, do they give expert answers?

We hope this guide has helped you choose a uPVC door supplier you can trust. If you're in Yorkshire, we'd love for you to consider Calder Windows. We're a trusted uPVC door company based in Wakefield – and we have more than 30 years of experience on our side. Plus, we're FENSA-approved and offer a 10-year warranty as standard.

What to do with an old conservatory

Mon, 24 Nov 2025 07:58:40 GMT

From creative makeovers to energy-efficient upgrades… Discover inspiring ideas for transforming your old conservatory.

Feel like your once-beloved conservatory has lost its shine? You're not alone.

Many UK homes built or renovated in the 80s, 90s or early 2000s came with conservatories that were the pride of the garden. But over time, they can start to feel a bit tired.

Maybe the space is too cold in winter, too hot in summer, or simply not getting the use it once did.

The good news? You don't have to give up on it. With a bit of imagination (and perhaps a little help from Calder Windows), your conservatory can enjoy a whole new lease of life.

Here are some ideas for what to do with an old conservatory, from clever repurposing to smart renovation.

1. Give it a thoroughly modern makeover

The simplest solution is to refresh and revitalise what you already have. A lick of paint, some fresh flooring and updated furniture could be all you need to transform the space instantly.

Think light and bright: repainting in pale shades and adding reflective surfaces can make your conservatory feel bigger and airier.
Update your flooring: replace tired laminate with wood-effect vinyl or natural stone tiles for a contemporary but practical finish.
Add texture and warmth: woven rugs, houseplants and soft furnishings can make the space feel inviting all year round.

If your existing structure is sound, a modern style update can make the space feel like new again without the need for major renovation.

2. Make it cosy all year round

Temperature issues are a common reason for older conservatories falling out of use. Traditional polycarbonate or glass roofs struggle to regulate heat, making them chilly in winter but sweltering in high summer. The result is a room that's only comfortable for a few weeks of the year.

A SupaLite tiled conservatory roof from Calder Windows is a game-changer. By replacing your old roof with an insulated, solid one, you can:

Maintain a comfortable temperature all year round.
Reduce noise from rain and wind.
Improve energy efficiency and cut your heating bills.
Give your conservatory a stylish new look, inside and out.

This is one of the most effective ways to breathe new life into your old conservatory and turn it into a fully functional living space.

3. Repurpose the space as a new kind of room

If your conservatory, as it was originally intended, isn't working for you anymore, why not give it a new purpose altogether? With some imagination, you can create a space that fits your lifestyle today.

Home office: natural light is proven to boost focus and productivity – perfect for remote working. Add blinds or thermal curtains for extra privacy and temperature control.
Hobby room or studio: love crafting, painting, yoga or music? Your conservatory can be set up to become your creative retreat.
Dining room: host dinners surrounded by garden views. With a properly insulated roof, you can dine in comfort, whatever the season.
Playroom for children: you can keep toys out of the way while giving kids plenty of space and sunlight to play.
Pet paradise: adding a comfy dog bed or cat tower will be a hit with your furry friend. They'll love basking in the warm light.

By reimagining the space as more than just an alternative lounge, your old conservatory can quickly find a new lease of life. It might just become one of the most useful and enjoyable rooms in your home.

4. Create a garden lounge or reading nook

Still want your conservatory to serve as a bridge between indoors and out? Here's an idea: turn it into a calm retreat rather than a full living space.

Add comfortable seating, soft lighting and indoor plants to create a garden lounge. Just like that, you've got the perfect place to unwind with a book or morning coffee.

You could layer in textures like wicker, linen and greenery to embrace a relaxed, natural aesthetic. Or, better still, upgrade the roof for improved insulation. That way, you can enjoy those peaceful moments, no matter the weather.

5. Upgrade or replace it altogether

Sometimes, an old conservatory simply isn't worth saving. Because, unfortunately, older conservatories simply weren't built for longevity like their modern counterparts.

Maybe the structure leaks, the frames are warped or the foundations are showing signs of wear. In that case, it might make more sense to replace the conservatory entirely.

Calder Windows offers full conservatory replacement and rebuild services, giving you a chance to design a space that truly fits your needs. Whether that's a modern garden room, a practical workspace or a light-filled extension, a new build can:

Add significant value to your home.
Provide better energy efficiency and comfort.
Deliver a space that blends seamlessly with the rest of your property.

You can even repurpose the old footprint to expand your kitchen, add a sitting room or create an open-plan dining area with bi-fold doors to the garden.

6. Make it "green" and sustainable

Updating your conservatory is also a great opportunity to make it more eco-friendly.

Choose energy-efficient glazing: modern double or triple glazing helps regulate heat and reduce energy loss.
Opt for sustainable materials: when replacing your roof or frames, look for responsibly sourced timber or long-lasting uPVC.
Insulate and ventilate: proper insulation doesn't just make your conservatory more comfortable. It lowers your carbon footprint, too.
Add solar shading or smart blinds: these can reduce overheating in summer without blocking natural light.

A renovated conservatory with energy-saving features can be as kind to the planet as it is to your wallet.

7. Or simply… enjoy it again!

Sometimes, it's not about changing the structure at all, but changing how you approach the space.

Reclaim your conservatory as a space for the simple joys. Your morning coffee as you ease into the day. Quiet reading when it's wet out. Afternoon tea with an old friend. Or an evening glass of wine surrounded by the garden.

With a few small upgrades, such as replacing draughty doors or sealing windows, your conservatory can still be the heart of your home.

Ready to revive your conservatory?

At Calder Windows, we've spent more than 30 years transforming tired conservatories into beautiful, practical living spaces.

Whether you want to install an insulated tiled roof or invest in a full conservatory rebuild , don't hesitate to get in touch with our team . We can help you fall in love with your space all over again.

Commercial uPVC windows: a buyer's guide

Mon, 17 Nov 2025 17:58:12 GMT

Are you looking for uPVC windows for a commercial installation? Learn the key considerations in our jargon-free glass guide.

Are you looking for high-quality windows for a commercial installation? Then you'll have noticed one thing straight away. The world of windows is much more varied than you might first have thought.

Today's suppliers offer whole catalogues of different types of windows. The glass used. The material used for the frame. The energy efficiency rating. The decorative features.

In our opinion, this range of options is a horn of plenty – one that benefits project managers, window installers and building users alike.

But we're not going to deny there's a downside. That downside is a little something consumer behaviourists call "analysis paralysis".

With such a range of options available, how can you know which to choose? Why, for instance, should you use uPVC windows rather than timber, metal or some other material?

It's not long before a quick flick through a window catalogue can leave you howling at the moon.

That's why we've put together this buyer's guide to commercial uPVC windows. We cover:

The kinds of commercial uPVC windows available
The benefits of uPVC as a material
How we can help you get the materials you need

We hope it helps you in your next commercial project.

What is a uPVC window?

uPVC stands for "unplasticised polyvinyl chloride". It's a rigid and durable type of plastic used for window frames, doors and guttering.

The word "unplasticised" is important. Standard PVC is vulnerable to weathering, rot and corrosion. The lack of plasticisers in uPVC, however, makes it a highly durable, insulating and low-maintenance alternative to wood.

These qualities are ideal for window frames. They can be manufactured in a range of colours and finishes, they last for years and they keep the heat in and draughts out. At a time when the cost of living continues to soar, this can be a great benefit to homeowners and business owners alike.

Examples of commercial uPVC windows

The phrase "uPVC window" refers to the material used for the frames. Within this category fall several different types of windows. In commercial installations, these include casement windows, tilt-and-turn windows, fixed or picture windows and high-security windows.

Large-scale casement windows are designed to cover a wide area of a building's facade. They provide a high level of ventilation and insulation without obstructing the view. This can give a commercial building a wide, open aspect.

Tilt-and-turn windows also offer good ventilation, but they open differently from casement windows. Their inward-opening mechanism makes them easy to clean in high-rise buildings.

Fixed windows, sometimes known as picture windows, are large, fixed panes of glass often used for storefronts or other large facades. They maximise a building's views and can give commercial settings a modern aesthetic.

Whichever style you choose, high-quality uPVC windows now provide exceptional security thanks to their robust, multi-point locking systems, toughened glass and reinforced frames. This enhanced security is indispensable, no matter how big or small your business.

And like all modern windows, uPVC frames come in a range of styles and finishes. This helps your windows blend into the building as a whole and can even reflect your brand identity.

Why use uPVC windows in commercial applications?

At this point, you may be wondering why uPVC is the best material for commercial applications. Why not use metal, wood or composite materials?

In our view, there are four compelling reasons to choose uPVC. These are durability, energy efficiency, low maintenance requirements and cost-effectiveness.

1. Durability

uPVC is built to withstand harsh weather conditions. This is one reason we're confident enough to offer a 10-year warranty. It's also why uPVC is a popular choice of material for commercial buildings that have to put up with the Great British weather.

2. Energy efficiency

uPVC frames offer excellent insulation. They create a tight seal that keeps heat out in summer and in during the winter months. This means building managers are less likely to reach for the thermostat and the finance team is less likely to wince at your company's energy bills.

3. Low maintenance requirements

uPVC windows are easy to clean and don't require painting. All you need is a sponge or cloth and a gentle detergent solution. And because they're unpainted, they never need to be repainted and they never end up looking old and tired. This makes them a low-maintenance option in any commercial setting.

4. Cost-effectiveness

Finally, uPVC is a cost-effective solution, especially compared to metal. If you work with the right suppliers and installers, you're likely to get more bang for your buck.

What to look for in a uPVC window installer

It's a hard fact of life: materials are only as good as their providers.

Yes, you can invest in the best materials on the market. But if you work with a subpar supplier, you're likely to be faced with logistical complexities, delays and budget-eating downtime.

That's why it's so important to look for an installer that's experienced, that stocks high-quality materials and that provides great aftercare.

Here at Calder Windows, we tick all these boxes. With our 30+ years of experience, first-rate materials and 10-year warranties, we're a safe pair of hands for a commercial installation.

How we can help

Get your commercial uPVC windows from us and you're guaranteed a robust window that's easy on the eye, easy to clean, highly secure and energy-efficient.

What's more, you get to choose from a range of foils, finishes and designs. Want your window to fit in with your overall brand aesthetic? We've got you covered.

They're tough enough to come with a 10-year warranty – and with their toughened glass panes and multi-point locking systems, they provide a barrier against intruders.

So, what are you waiting for? If you're looking for a commercial uPVC window supplier in the Yorkshire area, get in touch today for a quick, competitive quote.

Are composite doors better than uPVC?

Mon, 10 Nov 2025 23:46:39 GMT

Are you in the market for a new door? Then you may be wondering whether to go for composite or uPVC. Explore the pros and cons in our guide.

Getting ready to buy a new door? Then you'll have noticed one thing. The best material for a door appears to depend on who you ask.

The timber merchants rate timber. The metalheads love metal. The composite companies push you towards composite. And the uPVC brigade have eyes only for uPVC.

Here at Calder Windows, we're not like that. We don't believe one size (or material) fits all. Different materials have different applications, and each one has its own advantages and disadvantages.

Whatever material you choose, you'll need a door that's secure, insulated, durable and affordable. If it can be personalised through a variety of design choices, even better.

The good news is that these can be achieved with pretty much any material. But in some respects, composite doors are the way to go – and in others, we'd recommend uPVC.

This guide is intended to help you navigate the babble of strong opinions. Whichever you choose, we hope you'll consider us to be your supplier and installer. Happy hunting!

What are composite doors?

A composite door is an exterior door made from a combination of materials. These usually include wood, uPVC, glass-reinforced plastic (GRP) and polyurethane foam.

These layered components create a product that's durable, secure and energy-efficient. In most respects, it's superior to single-material doors – although as we'll see, uPVC doors have their place.

Another winning feature of composite doors is that the outer "skin" can be moulded to look like a wooden door. This gives you a classic look with up-to-date weather resistance. Win-win!

What are uPVC doors?

uPVC stands for "unplasticised polyvinyl chloride". It's a rigid material used for window frames, doors and guttering.

uPVC doors are popular for their affordability, low maintenance and weather resistance. They often have a steel core that stops the door from warping or cracking.

So far, so similar to composite doors? Let's explore the key differences by looking at the pros and cons of each.

The pros and cons of composite doors

In our view, composite doors have only one drawback. They're more expensive than their uPVC counterparts.

As so often with doors and windows, however, a higher initial outlay can reap rewards in the long term. They say if you buy cheap, you buy twice. In the case of doors, if you buy cheap, you may end up having your door replaced altogether.

Our composite doors are extremely durable. Their strong construction and multi-point locking systems make them a barrier against bandits. They're also less prone to fading and discolouration in the British rain and wind.

Their thick steel core and sturdy sealing provide excellent insulation, making your home more energy efficient as well as more secure.

All modern doors are good at keeping the heat out in summer and in during winter. But composite doors are a step up. If you're putting sustainability first, composite doors are the way to go.

Finally, composite doors are available in a wide range of colours, styles and designs. They can look good in any property and complement any aesthetic.

The pros and cons of uPVC doors

For most purposes, uPVC doors do the job that composite doors do. They just do it at a slightly lower level of performance.

If you're on a budget, there's nothing wrong with a uPVC door. It's easy to clean and maintain. Some uPVC products on the market (including ours!) come with strong energy efficiency ratings. They're durable and can be customised to complement your existing house style.

The disadvantages are that uPVC does these things less well than its composite counterparts. While they're durable products, they can fade over time and have a shorter lifespan. They also come with fewer style and colour options.

When should you choose composite doors over uPVC doors?

In our opinion, both composite doors and uPVC doors have their place. They're both household staples for a reason. They both tick the boxes and keep your home safe, warm and secure.

There are, however, a few cases where we would choose composite over uPVC.

The first is if you want to make a statement and add kerb appeal to your property. The second is if you're extra hot on security. Those multiple layers of materials provide better protection against forced entry than their uPVC equivalents.

Composite doors also offer superior noise reduction. If you live on a busy road (or have busy neighbours), then composite can be a great choice.

But perhaps the best argument for composite doors is that they hold their value for longer. This is both because of the door's lifespan and because they offer great energy efficiency, reducing household expenses over time.

That said, uPVC is a perfectly serviceable material that's ideal for households on a budget. In premium properties, meanwhile, it can be a good choice for secondary entrances.

How we can help

Here at Calder Windows, we stock both composite doors and uPVC doors . Both come with warranties and are made with high-quality materials.

Your home's security, energy efficiency and aesthetic appeal are our business. Explore our range of doors today to see how we can upgrade your property at an affordable rate.

Home security at Christmas: how to keep festive thieves at bay

Mon, 03 Nov 2025 09:18:13 GMT

Worried about opportunistic thieves this Christmas? Find out how to ward them off – and the pivotal roles doors and windows can play.

Security is an all-year-round concern. But there are times of year when extra precautions are called for.

Summer holidays are one such time. Christmas is another.

It's not just that your house is more likely than usual to be housing some coveted gifts. It's also that you may be away for the holidays, leaving your home vulnerable to burglary.

There's no single way to increase your home security. There are doors to lock, tech to be invested in and favours to call in from neighbours, family and friends.

But whatever steps you choose to take, we're sure of one thing: you shouldn't forget about your windows and doors.

In a way, it's easy to see why. Windows and doors are the most commonly used access points for burglars.

But there's another, less obvious reason upgrading your doors and windows can help keep your home safe this Christmas. And this is that not all windows and doors are created equal.

For every door and window built for security, with durable materials and robust locks, there's another that leaves your home vulnerable to intruders.

Doors and windows are our speciality – so it's no wonder we're highlighting their importance. But they're far from the only security measure worth taking.

So, here are some steps you can take to keep festive thieves at bay this Christmas. Just make sure there's room for Santa to get down the chimney…

Lock everything

Obvious, right? Well, yes. But you'd be surprised by just how many people forget to lock everything.

And by everything, we mean everything. Doors and windows should be secured, including those on upper floors. And you should make sure not to forget sheds, side gates and garages while you're at it.

Not any old lock will do, however. Most locks on the market provide an acceptable level of home security. But if you want to go the extra mile, we recommend Yale locks.

There's a reason why Yale locks are recommended by the UK police force. They're super-secure – and given their high-level performance, they're pretty affordable too.

Here at Calder Windows, all our doors and windows are fitted with Yale locks or multi-point locking systems. It's a sign of how seriously we take home security – not just at Christmas, but all year round.

Take extra security measures

These days, the security industry is laser-focused on tech. If you can afford them, a home alarm system, smart video doorbell or motion-sensor security lights are all great ways to scare off burglars.

These are all external installations – but you can also make changes indoors to keep the light-fingered away.

You can invest in an automatic timer switch to turn on lights and radios in the evening. This gives potential thieves the impression that you're in. This is one way to achieve the "illusion of occupancy" – a key aspect of any home security effort.

Oh, and if your house is festooned with blow-up Santas and the like, make sure they're physically secured with cords and wires. You don't want to come home to find your festive display a shadow of its former self.

Keep your valuables out of sight

Thieves know that Christmas is a time of year when people have more valuables than usual in their homes. They also know some people might leave those valuables on display. Jackpot!

If you're worried about festive thieves, you should make sure to keep presents out of sight until Christmas Eve. That way, you're not dangling any baubles in front of any Yuletide opportunists.

Keeping valuable presents out of sight has an added bonus, too. Your family are less likely to fiddle with their presents, making for an even better surprise!

Home security when you're away for Christmas

Are you away for Christmas this year? If you're worried about burglars, you may want to create "the illusion of occupancy". This phrase refers to any attempt to give passersby the impression that you're home.

There are two key ways to achieve this. The first is to cancel deliveries – after all, if a potential thief sees your deliveries piling up, they'll know you're away.

The second way is to enlist a friend or neighbour to make it look like you're still at home. They can achieve this by collecting your mail, putting the bins out and even parking their car in the driveway.

You should also be careful not to make your whereabouts obvious online. Account set to private? By all means, let your followers know you're having a festive getaway. But if your account is public, think twice before advertising the fact that you're not home.

Upgrade your doors and windows

No home is truly secure without high-quality doors and windows. These are the most obvious access points for any thief scouting out your property.

In this context, however, "high-quality" means a few things. It means robust materials – preferably a uPVC or composite frame and toughened glass panes.

It also means the best locks in the business. At Calder, we fit our windows and doors with multi-point locking systems and Yale euro cylinder locks. These are the UK police force's lock of choice – and Yale offers £1,000 in compensation if the cylinder is broken by a bandit.

And finally, it means the materials used to make the windows and doors are from trusted suppliers.

Here at Calder Windows, we're confident enough about the quality of our doors and windows to offer a 10-year warranty.

It doesn't matter whether you're installing a small bathroom window, French doors or something in between. Security and quality go hand in hand – and we can provide both.

Are you looking for a door and window supplier that takes security seriously? At Calder Windows, we've been fitting high-quality, highly secure windows and doors in Yorkshire for more than 30 years. Get in touch today for a quick, competitive quote or visit our Normanton showroom.

Sash vs casement windows: the differences and benefits of each

Mon, 27 Oct 2025 09:18:06 GMT

Sash windows and casement windows can make a big difference to any home. But what are the benefits and differences? Let's find out.

What are windows for? This isn't a riddle or a philosophical conundrum. It's a question that can guide you in your window-buying journey.

Windows let the light in – but not all windows let in the same amount. Windows contribute to a building's appearance – but different models have different styles and associations. Windows increase airflow – but, well, you get the idea.

These considerations are relevant whatever window style you're buying – not least when choosing between two of the most popular varieties: sash windows and casement windows.

These two types of windows have been in use for centuries. Today's models add a touch of class to any property – but each has its own unique features and benefits. In this article, we explore them in depth to help you choose the right window for your home.

What are the differences between sash windows and casement windows?

Perhaps the most fundamental difference between sash windows and casement windows is the way they open.

A sash window consists of two glass-framed panels inside a larger frame. These overlapping frames can be slid up or down to open the window.

A casement window, meanwhile, opens like a door on a side hinge (occasionally it opens from a hinge on the top) and is operated by a handle or crank.

This is far from a merely mechanical difference, however. It affects the look of the window and the amount of light and air it lets in.

Aesthetically speaking, a sash window is a traditional affair. Even today, it's mostly associated with Victorian and Georgian styles. Casement windows, by contrast, are more modern-looking and can arguably be used in a wider range of homes.

Then there's the question of light and airflow. A sash lets in an adequate amount of light and air for most people. However, its two overlapping panels can obstruct the view, and the unit can't be opened entirely.

By contrast, the design of a casement window allows for extra airflow. The whole unit swings open like a door, letting in all the air you could want and providing an unobstructed view.

Both sash windows and casement windows are easy to maintain – especially when fitted with uPVC frames. Howeer, sash windows can need a little more maintenance due to their sliding mechanism.

What are the benefits of sash windows?

1. Style

Sash windows have a timeless elegance. Their period authenticity, sometimes underlined by glazing bars, makes them a popular choice for homeowners with a taste for period living.

That said, today's sash windows are customisable, making them suitable for a range of homes. You don't have to be an old soul to appreciate their elegant design.

2. Airflow

Sash windows offer good airflow. This allows you to regulate the temperature, improving your home's energy efficiency and reducing condensation.

3. Insulation

Modern sash windows offer good sound insulation. Whether you're trying to drown out a noisy neighbour or your own noise, a sash window acts as an effective barrier.

4. Security

As well as keeping out noise, sash windows can keep out intruders. Modern varieties are made with robust glass and fitted with multi-point locking.

5. Easy maintenance

Finally, sash windows are low-maintenance – especially if you go for a uPVC frame. A simple spray and wipe once or twice a week will keep them in sparkling condition for years.

The bottom line

A sash window is an impressive and tasteful addition to any home – one that provides energy efficiency, ventilation and sound insulation. Some people, however, may prefer to go for a casement window.

What are the benefits of casement windows?

Casement windows have a lot of the same advantages as sash windows. They're durable, secure and energy-efficient and help reduce noise. But the reason for choosing one over the other isn't just a question of price.

There are two other factors at play. One is the question of size. Casement windows can be custom-made to fit almost any aperture. Sash windows, however, have a minimum opening size to accommodate their sliding sash design.

The other reason you might go for a casement window over a sash window is the superior ventilation and views it can provide.

Because a casement window opens like a door, it lets in plenty of light and air. For some people, this is more important than the antique charm of a sash window.

The same goes for views. A sash window is split in two by a horizontal bar – and in some cases, by multiple decorative glazing bars. If you want to enjoy your view to the fullest, a casement window may be the way to go.

How we can help

Here at Calder Windows, we stock both sash windows and casement windows . Like all our products, they're stylish, energy-efficient and weather-resistant – and they can be customised with an appealing range of colours and finishes.

Plus, with more than 30 years in the trade, we guarantee a professional and friendly service.

Frequently asked questions

French doors vs patio doors: which are best for your home?

Tue, 21 Oct 2025 19:03:11 GMT

Struggling to choose between French doors and patio doors for your property? Explore the pros and cons.

When it comes to doors and windows, today's homeowners are spoilt for choice. Whatever style you have in mind, there's something in a showroom or online store with your name on it.

But this unparalleled level of choice has a frustrating flipside. When there are so many options to comb through, how on earth are you supposed to make a decision?

Here at Calder Windows, we've been furnishing the people of Yorkshire with high-quality doors and windows for more than 30 years. So, if you want to know the pros and cons of different windows and doors, you've come to the right place.

In this article, we look at French doors and patio doors. These are two types of doors typically found at the back of a house or the front of a conservatory.

Both help bring home and garden closer together. But which one is right for you? It depends, as these things so often do, on your specific tastes and requirements.

When someone comes to us for advice, we don't tell them our preference without any further questions. Instead, we listen to their specific request. How big is the room? Do they like a specific era or design style? Are they looking to improve the value of the property as well as its appearance?

It's only by answering questions like these that we can give them our informed opinion. We hope this blog post does a similar job – guiding you through the most salient factors to help you make the right choice. Good luck!

What are the differences between French doors and patio doors?

They open differently

The main difference between French doors and patio doors is how they open.

French doors swing open on hinges. Like a standard door, they can be opened wide. Patio doors, by contrast, slide horizontally on a track.

They look different

The difference between the two types of doors isn't purely functional – it's also aesthetic.

French doors consist of two hinged, glazed doors. They have a classic look. If it weren't for the modern frame, you could be forgiven for thinking they were from the 19th century rather than the 21st. Sometimes, the main door panels are split into smaller squares or rectangles.

Patio doors typically consist of two large overlapping panes. A window buff might think of it as a large sash window laid horizontally. Its size makes it function almost like a picture window – and it has a similarly sleek and modern look.

They have different space requirements

Another difference between French doors and patio doors is how they interact with the existing space.

French doors need space immediately in front of them to swing into. If they open out onto the garden, this isn't often a problem. However, it can have an impact on the amount of furniture you have room for.

Patio doors don't need this space to swing in. Instead, they slide along a track, making them ideal for areas where space is at a premium.

What are the benefits of French doors?

In our opinion, there are four main benefits of French doors.

1. Security

Most modern French doors are fitted with laminated glass and multi-point locking systems. This makes them exceptionally hard to break or break into. When a set of French doors is split into smaller glass panels, this security only increases.

2. Style

French doors add architectural interest to any property. In turn, this can increase the market value of your home.

3. Versatility

French doors are versatile. Here at Calder Windows, we provide French doors in a range of appealing colours and finishes. Whatever your taste, we can help you choose a set of French doors that will blend into and enhance your property.

4. An outdoors-indoors feel

Finally, French doors bring the outdoors in. This can help create an airy environment for entertaining, a sense of spaciousness or simply a pleasant, welcoming vibe.

What are the benefits of patio doors?

Patio doors have the same benefits as French doors. They're secure. They add aesthetic interest to your home. They're versatile. And they bring the outdoors in.

However, patio doors have several benefits that French doors don't.

If your back room, conservatory, patio or garden is on the smaller side, French doors may take up too much room. In this situation, patio doors are the right choice to make.

And if you want a more modern aesthetic, patio doors are the way to go. Their sliding action and large, sleek surfaces give them a modern look that French doors lack.

Finally, there's the question of ventilation. French doors are either open or closed. Patio doors, however, can be partially opened to control the airflow more precisely.

What should I look for in a French door or patio door?

When buying a set of French doors or patio doors, there are several things to keep an eye out for.

They should be built to a high standard. They should be made with durable materials – toughened or laminated glass and a uPVC frame will do the job nicely. They should be easy to open and easy to keep in good condition. And they should keep the heat in as much as possible.

Your best bet is to work with a supplier that's experienced, professional and friendly. They'll be able to fix you up with the doors you need and install them with minimal disruption.

How to improve energy efficiency at home

Mon, 13 Oct 2025 16:08:56 GMT

Are you looking for ways to improve your home's energy efficiency? Here are 7 positive changes you can make.

When the cost of living is high, homeowners and landlords alike are looking for ways to cut costs. And no money-saving plan is complete without considering the question of energy efficiency.

Energy efficiency isn't just one thing. It covers everything from light bulbs to draught excluders, from thermostats to windows.

At its most basic, however, energy efficiency is about getting more bang for your buck. An energy-saving light bulb, for instance, does the same job as a standard light bulb but uses less energy. And less energy means less money on bills.

But saving money isn't the only reason people are pursuing energy efficiency with more enthusiasm than ever. It's also because energy efficiency forms a key part of green strategies, sustainability initiatives and other forms of environmentalism worldwide.

In other words, improving your household or property's energy efficiency can cut your carbon footprint as well as your energy bills. It's a win-win situation – but how do you make a start? Here are seven options you could explore.

1. Check your heating controls

Did you know that the controls on your boiler and thermostat can make a difference to your annual energy spending?

MoneySavingExpert reports that "dropping the temperature by one degree could save around £90 a year on average for a typical home".

Savings can also be made by reducing the flow temperature on a combi boiler. Done right, this means the water heating your radiators is hot enough to warm your home but less hot than most in-built settings.

On its own, tweaking your heating controls won't make a noticeable dent in your energy bills. But as part of a broader strategy, it can help improve your home's energy efficiency.

2. Know how much you're spending

It's not immediately obvious how much you're spending on electrical appliances. But until you find out, it'll be hard to make meaningful changes to your usage and to your appliances' energy efficiency.

Citizens Advice has a handy guide to the average cost of using appliances and simple ways to save money in this area.

These include checking your tariffs and finding out whether there are cheaper times of the day to use your appliances.

As well as checking the cost of your appliances, you can also look into using energy-saving light bulbs. Be aware, however, that some energy-saving light bulbs are more energy-saving than others.

3. Block draughts

If your home has a draught, it's not just air that's trickling away – it's money, too.

That's because you'll likely compensate for the draught by cranking up the heating. Instead, you should tackle the problem at its root by draught-proofing your floor, window, chimney or door.

We've shared a few ways to draught-proof uPVC windows before. If the window is old and draughty, however, you may want to upgrade it to a more modern, energy-efficient model.

4. Don't use portable heaters unless you absolutely have to

If your heating is broken, it can be tempting to use portable electric heaters. But if energy efficiency is your aim, you should only do this as a temporary measure while waiting for the repair.

Portable heaters, you see, are much more expensive to use than central heating. They have their uses, especially if you need a short blast of heat. But as a long-term solution, they're bad for your energy bills and your carbon footprint.

5. Bleed your radiators

Left unchecked, radiators can fill with trapped air. This leads to cold spots at the top of the unit and stops it from fully heating up. The result? You're paying more money than necessary to heat your home.

The solution is to bleed your radiators. This involves releasing the trapped air and restoring the unit's original functionality.

You know it's time to bleed a radiator if:

It's taking longer than usual to heat up
It gurgles
You can feel cold spots at the top

6. Make home improvements

So far, we've looked at changes you can make to appliances and draughts in your home. But you can also improve its energy efficiency by making more substantial home improvements – and increase your home's value in the process.

There are two key ways to go about this. The first is to improve your home's insulation, whether in the walls, floors or attic. Windows, too, have insulating properties.

Secondly, you can explore alternative heating methods like solar panels or heat pumps. These require a high initial outlay but can help you save in the long run.

If you're a homeowner, you can make these changes yourself. If you're renting, you could ask your landlord to do it. It's worth noting, however, that if a private landlord makes home improvements, it may be reflected in a rent increase.

7. Upgrade your windows

Finally, there's our speciality: the energy-saving world of windows.

Once upon a time, windows were fairly flimsy. For all their advantages, they weren't great at keeping the heat in – or out.

Today's windows are another story. They're built to be energy-efficient and to help regulate your home's temperature all year round.

Despite this, many homes still have old-school windows that do nothing but bump up bills. If this is the case in your home, we can help.

We provide double and triple glazing as well as uPVC frames. These modern units create a tight seal and stop the heat from escaping.

But our windows aren't just energy efficient. They're also cost-effective and secure, with multi-point locking systems as standard and U-values as low as our prices.

At Calder Windows, we've installed, repaired and replaced windows in Yorkshire for more than 30 years. Looking for high-quality uPVC replacement windows to boost your home's energy efficiency? Get in touch today to discuss your needs and request a quick, competitive quote.

Using your conservatory as a dining room: ideas and inspirations

Mon, 06 Oct 2025 08:17:08 GMT

With a bit of planning, a conservatory can make an excellent dining room. Find out how in our handy guide.

One of the best things about having a conservatory is the range of uses it can be put to.

After all, a conservatory is just a room. Sure, it's a standalone room with a distinctive style. But like any room, you can do with it what you will.

A conservatory can be a place to read, relax, grow plants, do yoga, answer emails or take calls. Some people even use their conservatory as a dining room.

It's easy to see why. A conservatory dining room is like a restaurant in your back garden – albeit one where you have to do the cooking. You get an al fresco dining experience with a roof over your head and the light flooding in.

What's more, a conservatory dining room is a relatively rare addition to a home. This can make it more attractive to buyers should you decide to sell.

Sounds good, right? But before you start shifting the table and chairs into the garden, you'll need to do a bit of planning. Here are some things to keep in mind.

The roof

Different conservatories have different kinds of roofs. Each has its own advantages and disadvantages. But in the case of a conservatory that doubles as a dining room, you want a roof that provides insulation. (And that won't sound like cutlery chucked down the stairs whenever it rains.)

At Calder Windows, we provide SupaLite solid roofs . One of these will make your conservatory a place you want to be in all kinds of weather. What's more, it's built to last and looks good, too.

Other options are available – but for our money, a SupaLite roof is the homeliest of them all. Whether you're entertaining guests or having soup for one, it can make a big difference to your dining room set-up.

Heating

It's a tale as old as time. An eager homeowner buys a conservatory, anticipating hours of leisure time in every season.

Instead, they find it a sweat lodge in summer and a fridge freezer in winter. Disillusioned, their would-be haven ends up as a dumping-ground for household detritus.

This is an all too common complaint from conservatory owners. But it's far from inevitable. A good, modern conservatory will come fitted with insulated glazing that helps maintain a comfortable temperature all year round.

But if it's still a little chilly in winter, you could consider investing in a conservatory heating system.

It could be as simple as a small radiator or as complex as underfloor heating. You can also look into thermal blinds or curtains and cooling systems for summer. We covered the most common options in our conservatory heating guide .

The truth is that conservatory dining rooms require a bit of forethought – both at the planning stage and when you're using them for dinner. You may find you need to warm the conservatory up before you start serving the food.

Furniture

Conservatory furniture is a world unto itself. In the case of a conservatory dining room, you want furniture that's economical with space, comfortable for diners and congruent with the overall vibe.

Comfy seats, rugs, cushions and throws all help in this department. Tables and chairs made from wood, wicker or rattan can enhance the sense of indoor-al-fresco dining.

Plant life, too, can make a difference – even if it's just a tastefully placed pot plant in the middle of the dining table.

If you don't have much space to play with, don't despair. You could invest in some foldable furniture or modular seating.

Still need inspiration? Check out our favourite conservatory furniture ideas .

Flooring

When food's on the table, spills are a possibility. What's more, a conservatory doubling as a dining room will see a lot of footfall.

For this reason, you want to get flooring that's water-resistant and which doesn't highlight any spills or stains.

Wood is a strong choice, as are tiles. Be aware, however, that not all floor materials are compatible with underfloor heating.

Most people see conservatories as a place to unwind. For this reason, you may want to cosy up the place with some rugs.

Lighting

One of the great advantages of eating in the conservatory is the natural light that comes flooding in. But if you want to eat in the evening or during the winter months, you'll want to invest in some creative lighting.

Chances are, you'll want to save on space. For this reason, ceiling lights and wall-mounted lights are the order of the day. If you've got room, you could also include a floor lamp.

Or why not have dinner by candlelight? When lighting your conservatory dining room, the only limit is your imagination.

The finer details

Plants. Place mats. Pictures. Tablecloths. All these little details can add to the cosiness and overall ambience of your conservatory dining room.

It doesn't matter whether you're entertaining guests, having a family dinner or eating alone. Small touches can make a big difference. Be sure to give them some thought when planning your conservatory dining room.

Flush casement windows: the pros and cons

Mon, 29 Sep 2025 07:19:47 GMT

Flush casement windows make for a premium addition to any home. Explore the pros and cons in our guide to this versatile type of window.

If eyes are the window to the soul, then windows are the soul of the house. In other words, your choice of windows can say a lot about you.

Casement windows, for instance, are a sure sign of sophistication. These hinged window units open outwards like a door. They look like a picture window, maximising the views from and the natural light in your home.

But unlike picture windows, they can be opened to let in a cooling breeze or shut to keep in the warmth.

When it comes to casement windows, versatility, aesthetics, ventilation and energy efficiency are the order of the day. But did you know there's more than one kind of casement window?

Standard windows have a protruding sash, sometimes known as a "lipped" sash. But with a flush casement window, the sash sits straight within the frame. When the window is shut, it's completely smooth and sleek.

So, why choose a flush casement window? And what are the potential drawbacks of getting one installed?

Let's find out.

The pros of flush casement windows

Versatility

There's no denying that a flush casement window is a smart and elegant addition to any building. Best of all, it can complement pretty much any style of architecture.

There's a reason why listed buildings and homes in conservation areas sometimes go for flush casement windows. They look the part, mimicking classic timber styles.

But they also blend in with more modern varieties of architecture. This versatility is one of the key advantages of this clean, classy window style.

Energy efficiency

Once upon a time, windows were bad at keeping the heat in. But today's modern materials and modern designs mean you can have an elegant window with no compromise on energy efficiency.

At a time when homeowners, urban planners, councils and governments are all prioritising sustainability, energy efficiency is a must. Flush casement windows are good for your energy bills – and for the planet.

Easy upkeep

Life's too short to be scrubbing windows on the regular. Flush casement windows can be kept spick and span with just a soft cloth and a mild detergent.

Soft and mild are the important words here. Anything coarse or harsh can damage the finish.

Flush casement windows are also durable. This means you're highly unlikely to have to replace them anytime soon. There's a reason why we offer all our customers a 10-year warranty on our windows…

Enhanced security

Today's flush casement windows come with multi-point locking mechanisms as standard. These help turn your home into a fortress.

This is true of most modern windows, of course. But flush casement windows have a secret weapon.

From the outside, they look like fixed windows. Burglars are less likely to try to get in through a window that appears unopenable.

Noise reduction

Tight seals and toughened glass mean improved noise reduction. So, if you want soundproofing as well as stunning views and an elegant appearance, flush casement windows could be just what you're after.

Ventilation

Flush casement windows can open fully. This makes them ideal for letting in a breeze and blowing away the cobwebs.

The cons of flush casement windows

For all their good points, flush casement windows aren't perfect. In our view, there are three main drawbacks.

First, they're not as widely manufactured as other windows, including other types of casement windows. This isn't a problem until you need to find a replacement part.

It's one reason why you should always get a professional to install your flush casement window. Unless you're highly confident and experienced, a professional will significantly reduce the chances of problems with parts in the future.

Related to this point is the fact that flush casement windows require a higher initial cost than some other classic window styles.

For some, this will be an instant turn-off. But if you have the funds, a flush casement window will pay dividends down the line. This is partly because of their longevity and partly because of their energy efficiency.

Thirdly and finally, you'll find a more limited selection of styles on the market than for other types of windows.

You may not be able to find the exact style you want. But the styles that do exist are elegant, sophisticated, smart and above all, versatile.

Whatever kind of building you live in, a flush casement window can add a great deal to the exterior. Meanwhile, the interior will benefit from increased natural light and outside air.

Investing in a flush casement window is a big decision. But in our view, the pros far outweigh the cons. There's pretty much no building a flush casement window won't improve. Seriously!

Why invest in custom bifold doors?

Mon, 15 Sep 2025 21:19:21 GMT

Custom-built bi-fold doors – are they worth it? Discover 6 ways these nifty doors can add value to your home.

Bifold doors go by many names. You might see them marketed as "folding sliding doors", "concertina doors", "interior folding doors" or, when used as room partitions, "sliding room dividers".

But whatever you call them, bifold doors can offer a touch of class to any home, snugly fitting into irregular openings and connecting your home and garden.

And when they're custom-built, they can be tailored to your personal requirements – from materials to colour schemes, from the way the doors are configured to hinges, handles and other hardware.

That's all well and good, you say, but aren't they a little on the expensive side? For many people, the answer is yes – but in our opinion, it's an investment well worth making. Here are six reasons why.

1. They fit perfectly

Custom bifold doors are custom-built. That means they're built for your home, not anyone else's.

Above all, this means they fit perfectly into any aperture. But this perfect fit enhances their performance, too.

Glass doors aren't just there to look through, after all. They're also there to increase insulation, security and noise reduction. All of these are enhanced by a snug, custom-built fit. This is especially true if you go for a model with modern materials.

Whatever opening you're trying to fill, custom bifold doors can do the job – and then some.

2. They enhance natural light

It would be hard to overstate the importance of natural light in the home. Yes, electric light can create mood – but during the day, is there any substitute for natural light pouring through the windows?

This is where custom bifold doors come into their own. They let the light come flooding in through clear, sturdy glass panels. This can help create a warm, welcoming space for you, your family and your guests.

This isn't just a question of aesthetics, however. More natural light means less electric light – and less electric light means lower energy bills. It's one of the key ways that bifold doors offer a healthy return on investment.

3. They connect the indoors with the outdoors

Do you want to provide seamless access between your home and your garden? There are many ways to achieve this – and custom-built bifold doors can play a pivotal role.

There are two sides to this. First, you get an almost uninterrupted view of your garden from inside. And secondly, you can fling open those doors and let the fresh air in.

It's a fantastic way to increase your home's homeliness and make the back of your house a perfect pottering spot.

Of course, bifold doors don't have to open out onto the garden. They can also be used as room partitions. In either case, the result is the same: more space and more freedom of movement in your home.

4. They're secure

When investing in doors and windows, security is a crucial consideration. Luckily for you, modern bifold doors are built to provide high levels of security.

This is mainly because new models are fitted with multi-point locking systems. These lock the doors at the top, middle and bottom of the frame.

On top of this, modern units are made with toughened or laminated glass. These are exceptionally hard to break, providing peace of mind as well as peaceful views.

5. They can add value to your property

Custom bifold doors are an investment – and we mean this both figuratively and literally.

Figuratively, because they'll give your home a glow-up you'll enjoy for years to come. Literally, because it's a classic case of a home improvement adding to the property's resale value.

Leaving aside their aesthetic appeal, modern bifold doors may call out to a buyer looking for an energy-efficient home. And at a time when sustainability is climbing many people's agendas, this is a case of when rather than if.

6. They come in a range of styles

Custom bifold doors aren't only custom-sized. They can also be manufactured in a wide range of materials and finishes, and with a wide range of door furniture.

The frames can be made from timber, aluminium or uPVC, each with its own look and performance. They can be painted any colour under the sun, matching your home's unique aesthetic.

Then there's the question of door furniture. A good door and window supplier (hello!) will have an array of handles and hinges in stock. These can help you find the bifold doors that reflect your personality.

At the end of the day, custom bifold doors can add character and value to any home – and they can be customised to make a perfect fit.

Frequently asked questions

At Calder Windows, we supply and fit bifold doors to customers in Yorkshire – and we've been doing so for more than 30 years. Are you in the market for a modern, custom-built set? We'd love to discuss your options with you. Get in touch online today or call 01924 897 040 to speak to our team.

Draught-proofing uPVC windows: 7 solutions that really work

Mon, 08 Sep 2025 22:55:11 GMT

Struggling with draughts? The problem may be your uPVC windows. Find out how to fix the problem – and when it's time to get new windows.

Are you feeling a draught? Have you traced the problem to your uPVC windows? Then it may be time to upgrade your draught-proofing – or get a new set of windows entirely.

Of course, draughts are only a problem with old or inferior uPVC windows. One of the main draws of uPVC as a material for window frames is precisely that it's durable and draught-resistant.

But you may have an old window that's starting to show signs of wear and tear. If so, there are several steps you can take to address this issue. Most of these are simple jobs you can do in an afternoon.

You may find, however, that these solutions are stopgaps and the problem returns sooner or later. In this situation, you may find it wiser to replace your windows.

Modern windows like ours are built to last. They're made of durable materials that won't decay and let in those unwanted draughts.

Still unsure? Here are seven ways to draught-proof your uPVC windows.

1. Silicone sealants

If the problem is caused by small gaps or cracks, you can fill them with silicone sealant. Before you do, make sure you're using a sealant intended to be used with uPVC.

The process is simple. Get your high-quality silicone sealant and apply the gel to the edges of the frames. It will harden and keep out the draught.

2. Weatherstripping

Weatherstripping is a foam strip or rubber seal that's applied to the gaps around doors and windows. It helps keep out air, moisture and draughts by creating a tight seal.

There are several types of weatherstripping on the market. These include tension seals, brush seals, foam strips and sponge tape.

The main drawback of weatherstripping is wear and tear. You should probably replace your weatherstripping once every five years – more often if the window is in constant use. At a certain point, you may decide that a new window is more convenient and potentially more cost-effective.

3. Check your hardware

Window hardware includes locks, handles and hinges. All these can affect the overall performance of a window because they all help seal the frame.

If your uPVC window is causing a draught, check the hardware to ensure it's all functioning properly. If not, you should get new hardware – or a new window.

4. Draught excluders

Draught excluders do what they say on the tin. They're a simple and cost-effective way of filling in the gaps through which air is escaping.

Before you buy a draught excluder for your uPVC window, you should be aware that a draught excluder alone won't improve your window's energy efficiency. Moreover, a bad installation job can cause problems with moisture and condensation.

Draught excluders are a stopgap in both senses of the word. Yes, they'll help you draught-proof your windows. But they're no substitute for a brand spanking new window made with modern materials.

5. Curtains and blinds

Curtains and blinds can help keep out draughts – at least up to a point. They can be a good, quick fix if you want to reduce the problem without meddling with the window itself.

H3: 6. Window films

Another temporary solution is to apply a window film. This is a transparent film that partially insulates the window.

This is a cost-effective solution, but one that won't make the problem go away forever. Consider it a stepping stone on your way to fully addressing the problem, whether by fixing the frame or replacing your windows.

7. Replace your windows

The methods we've explored here will all help draught-proof your windows. Some are short-term solutions, and some will last for months or even years.

There may come a time, however, when the best thing you can do is replace your windows altogether.

This is because draught-proofing is only necessary with out-of-date products. A good, modern window made from sturdy modern materials won't need draught-proofing. In other words, draught-proofing is a sign that your windows are on their way out.

Yes, new windows can be expensive. But the improvements they'll make to your energy efficiency make them, in our view, a worthwhile investment. And that's before you consider the money you'll eventually have to spend on maintenance and repairs.

Five signs your windows should be replaced

They're more than 20 years old. This will mean they're made of old materials that don't offer optimum performance. Your home can do better!
There's noticeable and persistent condensation between the panes. Yes, these problems can be temporarily fixed. But if you want shot of them for good, new windows are your best bet.
The frames are warped or damaged. At a certain point, it becomes more cost-effective to replace than to repair. In the process, you'll get a new window or set of windows with superior energy efficiency, durability and security.
You want to make your home more energy efficient. Modern uPVC windows are a great step towards improving your home's energy efficiency – and not just because they get rid of draughts.
The problem won't go away. You can draught-proof to your heart's content – but if the problem lingers, it's time to replace your window.

Heating for conservatories: what are your options?

Mon, 01 Sep 2025 12:57:00 GMT

Looking for ways to heat your conservatory? Explore your options and weigh up the pros and cons.

If there's one gripe that unites conservatory owners across the world, it's heating. In an old, uninsulated conservatory, it can become a real pain in the glasshouse.

In winter, you need to blast a fan heater to make it even slightly hospitable. And in summer, it's like walking into the heart of the sun in a scarf and gloves.

We hear you. But the fact is that it doesn't have to be like this. Heated well, a conservatory can be a great place to park yourself all year round – not just when it's warm but not too warm.

There are other factors at play to make your conservatory more heat-retentive and energy-efficient. But your choice of heating system undeniably plays a big part.

As with so many things in life, the problem is the sheer level of choice on offer. There are many different ways you can heat a conservatory, each with its own advantages and disadvantages. So, how do you know you're making the right choice?

Well, we're here to help. Join us as we break down the different kinds of conservatory heating and help you decide which is right for you.

Heat pump systems

Heat pumps are having a bit of a moment. It's all thanks to the emphasis placed on governments, housebuilders and homeowners to reduce their greenhouse gas emissions and look for alternatives to fossil fuels.

Heat pumps work by transferring heat from outside to inside. In the plus column, heat pumps are energy-efficient, environmentally friendly, discreet and easy to maintain. They're also quiet – a blessing on those cosy and relaxed evenings in the conservatory.

In the minus column, they're expensive to install. Yes, you can save in the long run, but there's no getting around the fact that the initial outlay is more expensive than other options.

Electric radiators

Are you looking for a heating option that's quick and easy to install? Then a simple electric radiator could be just the thing for you.

The big advantage of an electric radiator is that you can just plug in and play. You don't have to spend time and money extending or re-laying your home's pipes.

They come in a wide range of shapes, sizes and styles. What all these specimens have in common, however, is compactness.

Electric radiators don't take up room. This can do wonders for the comfort and spaciousness of your conservatory.

What's more, they warm up and cool down at quite a clip. This means you're highly unlikely to overspend on your heating.

Infrared heaters

Do you want to feel like you're sitting in the sun without worrying about those nasty UV rays? Infrared heaters are the way to go.

These work by emitting radiation waves that heat objects – including humans! They warm up quickly and work efficiently, heating objects rather than the room as a whole.

Trench heating

Trench heating is a kind of underground heating system. It involves placing a radiator in an underground trench. Hot air rises through a grill and warms the conservatory.

In the plus column, trench heating is a highly efficient use of space. In the negative column, it takes time to warm up and can be expensive to install.

Underfloor heating

Like trench heating, underfloor heating is discreet and effective but slow to warm up and cool down. It also needs to be switched on before you use the conservatory.

In some cases, underfloor heating has to be laid when the conservatory is built. If not, you'll have to put up with some disruption while the installers get to work.

Finally, underfloor heating can't be laid under all types of floors. Solid wood and carpets are a no-go.

It's not all negative, though. If you can face these challenges, underfloor heating will effectively heat your conservatory all year round.

Extending your central heating

If you're in the mood for a home improvement project, you could consider extending your central heating. This involves lengthening the pipework and installing a radiator or two in your conservatory.

This can be a highly effective solution to your heating woes – not least because modern radiators can heat any space quickly and efficiently. Best of all, they can maintain that heat for hours.

Before you take the plunge, you should check building regulations. You should also be sure that your boiler and pump can handle the extension. Skip this step and you may have a broken boiler on your hands.

Log burners

Log burners can be a stylish, cost-effective and energy-efficient way of heating your conservatory – and in most cases, they don't require planning permission.

They do, however, require a lot of planning. You need to decide on the size and model of stove, its position in the conservatory and the size and position of the chimney.

You'll also need to give some thought to the kind of fuel you're going to use. This is especially important if you want to minimise your carbon emissions.

Air conditioning

Did you know that air conditioning can keep you warm in winter as well as cool in summer? The heat pump in the unit can draw in warm air from the outside. Naturally, this works best in areas with plenty of warm outside air.

High-quality conservatory roofing

Your choice of heating system isn't wholly responsible for the thermal efficiency of a conservatory. This also falls to the conservatory itself. The better the build, the less heat it loses.

If you have an old conservatory that's hard to heat effectively, you might want to consider installing insulated conservatory roofing .

Our roofing systems are built for thermal efficiency. This is partly down to the modern materials and partly to the quality of the insulation.

Replacing your conservatory roof is a big deal. But once you've made the decision, you won't look back. Just ask our customers!

Conservatory repairs: when to fix and when to replace

Mon, 25 Aug 2025 09:30:21 GMT

Is your conservatory in need of some TLC? Find out what you can do yourself, when to get the professionals in and when to replace it entirely.

For more than a hundred years, conservatories have provided sanctuaries for many homeowners. They're places to unwind, potter or entertain guests while watching the changing of the seasons.

But like almost everything in life, conservatories can start to fade, crack and show signs of age. This can make your conservatory a less appealing place to be in – and it can also chip away at the value it adds to your home.

Regular maintenance will help you. And a good-quality conservatory can last upwards of 50 years. But there comes a time when some conservatory owners will find themselves at a fork in the road. In one direction, repairs. In the other, replacement.

The path you take will depend on several factors. These include the extent of the damage, your aspirations for the conservatory and the respective costs of repairs and replacements.

Moreover, repairs fall into two categories: the ones you can roll up your sleeves and do yourself and the ones you need a professional for.

If you're a DIY don, there are plenty of repairs you can carry out yourself. But if you lack the skills, time or inclination, it may do better calling in a repairer.

In this article, we look at some common conservatory repairs – and ask which ones you can do yourself, which ones need the professional treatment and which ones mean you should cut your losses and get a new conservatory.

Gutters

Clogged or damaged gutters are a recipe for one thing: leaks. Leaks, in turn, can mean mould, damp and even structural damage – and structural damage can mean an expensive replacement job.

If you spot a leak, it's important to quickly identify the source and figure out whether you can sort out the problem yourself. Many homeowners have the skills and equipment to unclog a gutter or replace a section of guttering.

But if the whole gutter needs replacing, you should get a professional in. This will help increase the lifespan of your conservatory.

Draughts

Feeling the chill when you're trying to chill in your conservatory? You may need to draught-proof your windows, doors or roof.

Draught-proofing can be a straightforward DIY job: applying sealant or installing draught excluders, for instance.

If the problem requires secondary glazing or plugging large gaps, however, it's time to call in the repairers.

Getting rid of draughts doesn't only improve your time spent in the conservatory. It also helps you save money on energy bills.

Roofs

Over time, conservatory roofs can start to lose their lustre. Tiles come loose or get damaged. Leaks appear. All these issues can lead to water damage, which is a costly problem to address.

So, if there's a problem with your conservatory roof, chances are that you need a professional to look at it. The consequences of a poor job are too serious – and too expensive – to be done by an amateur.

Poor temperature regulation

It's a common complaint among conservatory owners – especially those who own older models. The conservatory looks delightful, but it's too hot in summer and too cold in winter.

This is probably because of inadequate insulation or ageing materials. It could be time to get the insulation updated – or to replace the conservatory altogether.

In either case, you need professional help to get the best out of your conservatory.

Window frames and door frames

If your window frames or door frames are defective, you could be compromising your conservatory's security as well as creating draughts and leaks.

Some issues with conservatory doors and windows can be dealt with by DIY: loose screws, for instance, or replacing worn seals.

If the door is hard to open, however, this may point to structural issues that need professional attention. The same applies if a pane, frame or lock needs replacing.

Condensation

Are your windows fogged or misted up? This is probably because the seal between the panes has failed. This isn't just a cosmetic problem. It can also scupper the energy efficiency of your conservatory.

It's a quick job but one for the professionals – unless, that is, you're willing to put the time in to learn skills, gather equipment and plan the installation.

Wear and tear

Chipped paint? Dirty windows? Scratched surfaces? All these cosmetic jobs can be done without professional help.

If, however, the wear and tear has caused cracks or warping in the structure of the conservatory, your best bet is to get a professional in to address the problem.

A word about warranties

Before you set about a repair, check to see if the issue is covered by your warranty. Here at Calder Windows, our conservatory installations are covered by a 10-year warranty. So, if you bought your conservatory from Calder within the last decade, you may be able to get the repair done by us.

When to replace a conservatory

Sometimes, the damage to a conservatory is too much to be repaired cost-effectively. As with a car, you may find it's better to write off your conservatory and buy a new one.

To decide, you first need to assess the extent of the damage. Small leaks, damaged seals and cosmetic damage can be easily sorted.

But if the damage is structural, you may find that repairs help with the problem but don't fix it entirely. This means you're likely to need more repairs down the line.

In this situation, it can be best to get rid of your existing conservatory and buy a new one – preferably one made from modern materials with a longer lifespan and a generous warranty.

As well as fixing your structural problem, this will be more cost-effective and energy-efficient. Lower energy bills, a longer lifespan, more comfort – if you have the means to fund it, a new conservatory is a no-brainer.

Can you paint aluminium windows?

Mon, 18 Aug 2025 07:43:13 GMT

Are your aluminium windows in need of a lick of paint? There are a few things to keep in mind before you get out the paint and brushes.

Since the 1950s, more and more homeowners in the UK have chosen aluminium for window frames, door frames and other features.

As a material for window frames, aluminium has plenty to recommend it. It's long-lasting and doesn't rust, meaning you get a good return on your investment. It's lightweight, giving your windows a sleek, modern look.

What's more, aluminium windows rarely need repainting. But "rarely" isn't the same as "never". Sometimes, you may find your frames looking a little on the tired side. And in that situation, you may wonder whether you can repaint them.

The answer is yes. However, painting aluminium frames is a little more involved than painting a wall. You need to choose your materials with care and prepare the surface before painting. But first, you need to choose a colour.

Pick a colour, any colour

Aluminium frames can be any colour under the sun. Your choice of colour will depend on your taste, of course, but also on the nature of your property.

Older properties often look good with a darker frame. Modern properties can benefit from neutral, minimalistic whites, blacks or greys. Alternatively, they can make a statement with bold primary colours.

Whatever colour you choose, you can't just slap on a coat of paint and hope for the best. First, you need to prepare the surface.

Preparation is all

When it comes to painting aluminium frames, preparation is essential. Cut corners and it won't be long before you're looking at a peeling, chipped frame.

First, clean the frames using a microfibre cloth and a cleaning solution. This could be isopropyl alcohol, a mixture of detergent and warm water or another mild solution. The mildness is important. Anything harsh or acidic could damage the frames.

Once you've removed the dirt and grime, you need to sand the frames. Take some fine-grit sandpaper and gently sand the surface. Your aim isn't to fully smooth down the surface. Instead, you want to rough it up. Once this is done, you should dust off any residue.

If there are stains left, douse them in baking soda or vinegar and wipe them off with a soft cloth.

What type of paint should you use on aluminium window frames?

Aluminium frames expand and contract with the heat. This means you need a type of paint that will move with the frames.

Acrylic is ideal for this purpose. On top of its flexibility, it dries quickly, meaning you can start cleaning more quickly than with other types of paint.

Alternatives include epoxy paints and oil paints. Oil paints, however, are quicker to crack and peel than acrylic paints.

How to paint aluminium window frames

There are a couple of precautions to take when painting aluminium frames. These are to avoid making a mess and to protect you against the fumes in primers and aluminium paints.

Before you start painting, cover the glass with paper held in place by masking tape. Cover any nearby areas that you want to keep clean. You may also want to put a dust sheet on the floor below the windows.

Primer and aluminium paint contain toxic fumes. At the very least, you should ventilate the area and wear a mask and gloves.

You're now ready to start painting. First, add primer. When you buy the primer, make sure it's suitable for metal surfaces.

Your aim is to create a smooth and even base for the paint. To accomplish this, apply the primer evenly to every part of the frame you intend to paint. You can do this with a spray or a brush.

Let the primer dry and check for bubbled or uneven areas. These can be smoothed out with sandpaper. Once smoothed down, wipe away any dust left behind.

Now, on to your chosen colour. You will need a minimum of two coats of acrylic paint. In some cases, you may need a third coat.

As with the primer, you should aim to apply it evenly and thinly. This will help you achieve a tough finish.

If you're using a brush, you can dab the paint into hard-to-reach corners and edges. These can then be smoothed out with the brush.

Finally, leave it to dry and lightly rub down the frames. Your frames should now be looking as fresh as a daisy.

How to maintain the finish on your aluminium window

As with many household tasks, your best bet when cleaning aluminium windows is to do it little and often. This stops the build-up of dirt and means you can do the job quickly.

Use mild detergent mixed with warm water and apply it with a soft cloth. Make sure to use a mild detergent, as anything more abrasive can damage your frames.

If there are any stubborn spots, you can attack them with a mixture of vinegar and water. Minor scratches can be covered up with paint. If the scratch is deep, lightly sand the area before applying paint.

Frequently asked questions

How to change locks on uPVC doors

Mon, 11 Aug 2025 18:59:46 GMT

Need to change a lock on a uPVC door? We've got you covered. Learn how to do it in a handful of easy steps.

If there's one experience common to homeowners, it's this. Every so often, you'll discover a new job needs to be done that you'd never considered before.

Changing the locks on a uPVC falls squarely into this category. Most of us accumulate a little knowledge about boilers, gutters and other household essentials simply by being alive. But few of us could happily explain how to change a lock without calling a locksmith.

Nevertheless, it's a job that needs to be done now and then. It could be that you're struggling with a faulty handle, a sticky key, a stubborn locking point or a door that wiggles in the frame. Whatever the reason, don't despair: this is a job that can be done in a matter of minutes.

You can, of course, call a locksmith. But this is one of those jobs where you can save time and money by doing it yourself.

The first thing to do, however, is to identify whether the whole multi-point locking strip needs replacing or whether you only need to replace the centre case. This is the part of the lock that the key goes into.

How do you change the multi-point lock on a uPVC door?

To change the multi-point locking system on a uPVC door, you first need to gather your tools. This will definitely include a screwdriver and may also include a drill and a rubber mallet.

First, you unscrew and remove the handles and cylinder. You then do the same for the lock strip, starting at the top and carefully easing it out of the door.

You then install your replacement lock. This should be the same model and measurements as the old one. Once it's screwed in, you need to reattach the cylinder and the handles.

Once that's done, it's time to test the lock from inside and outside.

How do you change the centre case on a uPVC door?

First, you need to remove the old centre case. It helps to know a little about the mechanism of a uPVC door lock before you start.

The key enters a barrel. This is a shaft of metal with a mechanism in the middle. When you turn the key, the mechanism is activated and locks the door in place. The barrel is held in place by a screw.

All you need to do is remove the screw or screws using a screwdriver or an electric screwdriver. Make sure the key is in and turn it to the vertical position. If the key is to one side, the internal mechanism will stick out and the barrel won't come out. Turn the key slightly until the barrel starts coming out.

Next, you need to buy a replacement lock.

Buying a replacement lock

A barrel has two measurements. It's split down the middle by a strip where the screw hole sits. You need to measure from either end up to but not including this middle strip. Add them together, and you have the measurements you need to buy a replacement.

You should also find out what brand the lock is. The name of the brand is likely to be on the metal strip in the door.

Finding a like-for-like replacement for your centre case or multi-point locking system will save you headaches down the line. You can buy a replacement lock online or from a local hardware store.

If you're unsure about the brand, measurements or other details of your lock, you could take the lock into a hardware shop. Alternatively, you could upload a picture to a lock supplier's website or send it to them in an email.

Now you've got your replacement lock, it's time to put it into action.

How to replace a lock

Replacing the lock is a piece of cake. Put the barrel back in the hole, reinsert the screw, then tighten it.

Test the lock to make sure it works – and voila! You've changed the lock on a uPVC door.

How we can help

Here at Calder Windows, we're highly experienced in both uPVC door repair and uPVC door replacements . All our doors come with a 10-year warranty – so if you're having trouble with the lock, you're covered.

Bay window sizes: how to ensure a perfect fit

Mon, 04 Aug 2025 08:09:00 GMT

Getting a bay window installed or replaced in your property? Read our guide to make sure you get the perfect fit.

Up and down the UK, bay windows add a touch of vintage class to homes, hotels and other buildings.

These traditional-looking windows can enhance both the inside and the outside of a property. They increase the amount of natural light coming into the front of the house. They create space, in some cases providing extra seating or storage.

Perhaps above all, they add vintage character and charm. But just because they have a premodern look doesn't mean they're built to premodern standards.

In fact, today's bay windows are made from modern materials like uPVC and toughened glass. This makes them robust and energy-efficient. On top of this, many are fitted with multi-point locking systems for extra security.

If you're looking to install a bay window or replace an existing one, you'll need to make sure it's a perfect fit. If you don't, you'll have to undo your work at a high cost. Here's how to make sure you get it right first time.

Standard sizes for bay windows

There are standard sizes for bay windows. These range in width from a minimum of three feet, six inches (101.6 cm) to 10 feet, six inches (320 cm) and in height from a minimum of three feet (91.4 cm) to a maximum of six feet and six inches (198.1 cm).

These standard sizes can serve as a rule of thumb when you're in discussions with an installer or supplier. In some cases, however, you may want to get a custom design. This could be the case whether you're installing a bay window as an extension or replacing an existing window.

Custom designs

While bay windows can come in standard sizes, you also have the option to get a customised design.

This customisation covers all aspects of the design and installation. You can choose how big the window should be, the materials it's made from and the angle at which it's installed. This last factor will affect the amount of natural light entering your room.

In terms of materials, you can choose between uPVC, aluminium and timber for the frame and different types of glass for the window. For instance, you may want frosted glass for extra privacy or triple glazing for extra energy efficiency.

The bay window can be configured in different shapes. Splay bays, circular bays and single bend bays are just some of the options. They can also be customised with window sills, seating areas and integrated storage spaces.

Customisation also covers the colour of the window frames. Here at Calder Windows, our frames come in all the colours (and shades) of the rainbow. Truly, the only limit is your imagination.

How to measure a bay window for blinds and curtains

Measuring blinds and curtains for bay windows isn't always an easy job, thanks to the bay window's unusual angles.

You'll need three sets of measurements for blinds and curtains:

The width of each window panel
The total length of the curtain pole or track
The "drop" (vertical length) of the curtains or blinds

When measuring for blinds, you should also take handles, vents and other obstructions into account.

Once you've got these measurements, you can either take them into the store with you or use them to order curtains or blinds online.

Do you need planning permission to get a bay window installed?

If you want to install a new bay window at the front of your house, you'll need to apply for planning permission. However, if you're replacing an existing bay window or installing one to the side or rear of your property, you won't need planning permission.

The exception to this is if you live in a conservation area or listed building. In these cases, more stringent rules apply and you might need planning permission – even if you're replacing an existing bay window.

In this situation, you should contact the Conservation Officer at your local council to find out if consent is required. You may also need to apply for Listed Building Consent .

How Calder Windows can help

Here at Calder Windows, we've been installing, repairing and replacing bay windows for more than 30 years.

We stock bay windows with frames made from uPVC and windows of toughened glass. These combine traditional aesthetics with modern functionality.

Each one has a multi-point locking system for your peace of mind. They're built to last, are low on maintenance and available in a range of attractive colours and finishes.

What's more, they're energy efficient. By keeping the heat in during the colder months and out when it's warm, you'll spend less on energy bills and cut your carbon footprint. This is all thanks to the high-quality glass we use.

And as if that wasn't enough, all our uPVC bay windows come with a 10-year warranty – so if you run into any problems, we've got you covered.

Frequently asked questions

Can you remortgage for home improvements?

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 28 Jul 2025 14:34:06 GMT

Looking to fund home improvements but don't know how? Explore remortgaging and other options.

For most people, most of the time, a mortgage is all about moving. But did you know that remortgaging can be a way of funding a home improvement project?

Whether you're looking to add value to your home or simply want to increase your comfort there, remortgaging can help you pay.

After all, most projects that qualify as "home improvements" aren't exactly small purchases. Extensions, solar panels, renovations – all require a decent amount of cash to get right.

Remortgaging works like this. Let's say you have a mortgage of £200,000 and you need £15,000 for a conservatory. You would ask either your current lender or a new lender for a new mortgage of £215,000.

Your repayments will, of course, go up – and in the long run, you'll be paying more than £15,000 on your conservatory. But it can be a nifty way of budgeting for a big project if you don't have the funds immediately at your disposal.

H3: Remortgaging vs borrowing more

Along with remortgaging, homeowners have the option of borrowing more to pay for home improvement projects.

The amount you can borrow – and the interest rate – will be affected by how much you have left to pay and how much the property is now worth. It will also be affected by your current financial situation rather than your situation when you took out the mortgage.

All this means you could end up paying a higher interest rate on your mortgage repayments. As with your original mortgage, the extra you add is secured against your home.

If you decide to remortgage, you should get quotes for your home improvements before approaching a lender.

Is it right for me?

Remortgaging to pay for home improvements works for some people and not for others. Here are some things to keep in mind before you go ahead:

You may get charged an early repayment charge (known as a "redemption fee" or "exit fee").
The remortgaging process can take a few weeks.
The older you are, the more difficult it is to remortgage.
If house prices fall, you could owe more on the mortgage than the house is worth (what's known as negative equity).
If you have less money in the future for any reason, you may struggle to meet your repayments.

What is LTV and how does it affect remortgaging?

Before you ask a lender to remortgage or increase your mortgage, you should find out how this will affect your LTV (loan-to-value) ratio.

This ratio tells you the percentage of your home's value that a lender will lend you. The higher the percentage, the higher your interest payments.

It may be that your new interest rate is higher than the interest on a personal loan. In this situation, remortgaging may not be for you.

Paying for home improvements with a lifetime mortgage

A lifetime mortgage is a type of equity release taken out by people in their 50s and older. It involves borrowing money against the value of your home. You take out a loan secured by your property – one that doesn't need to be repaid until you die or go into long-term care.

Lifetime mortgages aren't for everyone. If you don't pay back monthly, interest payments are "rolled up" and can quickly snowball. What's more, a lifetime mortgage can affect inheritance. For some people, however, a lifetime mortgage is a great way to pay for home improvements.

Will home improvements add value to your home?

The answer is "maybe". Sometimes, the work pays for itself because your new kitchen – to take one example – adds value to the property. But this isn't always the case.

It's also worth considering the ceiling price in your area. This is the maximum amount a buyer is likely to pay for a house in your area. If you get a new conservatory, for instance, you may nudge the property over the ceiling price, cancelling out the added value of the extension.

If your property is close to the ceiling price, it's worth checking with a local estate agent or financial advisor before you start planning a home improvement project.

More often than not, kerb appeal is a more reliable and cost-effective way to increase the value of your property.

Other ways to fund home improvements

If you decide against remortgaging for home improvements, there are other ways to fund your project.

The safest and most cost-effective is to pay from savings. If this isn't an option, you could consider paying by credit card or personal loan.

If you pay by credit card, make sure you're confident you can clear the full balance each month. If you don't, you'll have to pay interest.

Personal loans often have higher interest rates than mortgages. They are, however, paid back over a shorter period, meaning you can pay less back overall.

The key difference between a personal loan and a mortgage is that a personal loan isn't secured against your home.

As with all loans, make sure you take one out only if you're confident you can make the monthly repayments. If you don't, you're building up financial troubles for later.

You may be eligible for a further advance. This is where you borrow more from your lender at a different (preferably lower) rate than your mortgage. As with all these options, it's important to do the maths before committing to anything.

Can you remortgage after a home improvement project?

If you fund your home improvement project through a personal loan or savings, you could remortgage your home once the work is complete.

This is especially sensible if the changes have increased the property's value. You're now in a position to get a deal with a better LTV ratio. However, you shouldn't assume the improvements will improve your home's value.

Keep that glass shining: 5 of the best window-washing tools

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 21 Jul 2025 07:25:27 GMT

Want your windows to shine? Explore 5 of the best window washing tools to help you in your quest.

The Scottish poet and minister George MacDonald once penned a paean to cleaning windows. "What a difference it makes!" he wrote. "How it melts the filthy gloom!"

So far, so relatable. But the next two lines might be met with scepticism by many homeowners: "What a little more it takes / Much to brighten up a room!"

A little more , George? Really?

Let's face it: there's a reason why many people get a professional in to clean their windows. Doing the job well takes time and energy – two scarce resources in a busy life. Melting the filthy gloom isn't something you can strike off your to-do list in a matter of minutes.

On the other hand, the DIY approach is more cost-effective and can give you a greater sense of control over your castle.

So, if you are going to do it yourself, what tools do you need? Here are five of the best.

1. Microfibre cloths

Microfibre cloths are an indispensable ally in the war against grime – and they're essential for cleaning windows.

Opt for a rougher scrubber and you could damage the window permanently. Use rags or paper towels and you'll watch with frustration as the dirt gets moved around the glass. But use a microfibre cloth and you can watch the dirt go without leaving streaks.

On the subject of softness, the same principle applies to your cleaning solution. Make sure you're using a glass-friendly liquid to clean your windows. Harsh chemicals will only cause damage.

2. Window vacuum cleaners

Most window cleaning tools are all about wiping. But another way to get rid of grime is to suck it up with a window vacuum cleaner.

There's a plethora of handheld window vacs on the market. Some are rechargeable, while others require single-use batteries. Some can even be used to get rid of condensation.

What all of them have in common is their ability to suck up the residue left by your spray and microfibre cloth. The result: sparkle without sweat. Not bad!

3. Extendable squeegee poles

Do you have a top-floor window that's a pain in the neck to clean? Live in an upper-floor apartment? An extendable squeegee pole could be a good investment.

You could, of course, get up there with a ladder. But not everyone feels safe on ladders, even with a friendly pair of hands securing it in place.

An extendable squeegee pole lets you clear up water and debris from windows without mounting a ladder. And it helps you reach even the most awkward, hard-to-reach spots.

It does, however, need to be used in conjunction with other tools. While it's great for removing water and debris, it's not so hot on edges, corners and other tight spots.

4. Robotic window cleaners

In 2011, a Korean firm brought out the windoro – the world's first commercially available robot window cleaner.

Since then, a range of models have become available. They differ in details, but all help you reach the same goal – hands-free window cleaning.

Today's models, such as the Hobot and Ecovacs Winbot, can be attached to windows with suction pads. Once attached, they use sensors and AI to navigate the surface. Some spray the surface with cleaning solution. All wipe away cleaning solution with microfibre pads.

Robot window cleaners get mixed reviews. At their best, however, they can be a valuable addition to your cleaning arsenal. And for those of you who love smart technology, many models can be controlled with an app.

5. Magnetic window cleaners

Need to clean an upper-floor window but don't want to use a ladder or an extendable pole? You could explore the world of magnetic window cleaners. These have one overriding advantage: they're double-sided.

You attach one part of the cleaner to the inside of the window and the other part to the outside. The magnets on each part create a firm grip.

As you wipe down the inside window with one part, the outside part follows. This lets you tackle two jobs with one tool and get sparkling windows inside and out.

Other tips and considerations for cleaning windows

Make sure you prep your window frames and handles before cleaning the glass itself. Otherwise, you risk dragging dirt from the frame onto the glass.
Keep your materials and tools close at hand. If you don't want to worry about picking them up and putting them down, why not invest in a work belt?
Spray the windows from top to bottom and then clean them with a zig-zag motion. This helps keep streaks to a minimum.
Many argue that you get better results cleaning windows on a cloudy day than when the sun is shining. This is because sunshine can evaporate the cleaning solution before it's done its job.
When you're done, clean your equipment so it's ready to use next time.

8 space-saving furniture ideas for a small conservatory

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 14 Jul 2025 12:18:24 GMT

Is your conservatory on the small side? Explore 8 ways to make the most of the space you've got.

Since the Victorian times, conservatories have had a classic look. You know the one we're talking about: glass windows, a steel frame and, inside, lightweight wooden furniture upholstered in muted creams and beiges.

Many customers want to recreate that aesthetic. What's a conservatory, you might think, without rattan, wicker, cane or willow?

The trouble is that traditional furniture can be difficult to fit into a small conservatory. Sure, you can get in a table and a chair or two – but in many cases, you'll find that's your allotted space already gone.

So, what's the solution? Luckily for you, there are many ways to save space in your conservatory and make it feel spacious and uncluttered.

These range from the furniture itself to the way you arrange it in the conservatory. It also includes careful use of plants, mirrors and storage space.

1. Small is beautiful

Small furniture is best for a small conservatory. Sounds obvious, right? Yet many conservatory owners don't know the range of furniture available.

Corner sofas, two-seater sofas and armchairs with narrow arms all help you maximise the space in your conservatory. The same goes for folding chairs and tables.

And if you want to spend evenings in your conservatory curled up with a book or a box set, why not get a floor lamp with a table attached?

2. Let the light in

When choosing furniture for a small conservatory, you should go for objects that won't block the light.

This is partly a case of placement. The trick is to balance vertical furniture that doesn't take up floor space with horizontal furniture that doesn't block the light. The result? A conservatory that makes the most of natural light all year round.

3. Use mirrors

There's nothing quite like a mirror to give the illusion of depth. Careful placement can maximise both light and space. After all, there's a reason mirrors are such a staple in stately homes and palaces – they make the rooms look even grander!]

You can achieve a similar effect with glassware. Why not scatter light with a glass ornament or a tall vase?

4. Smart storage

No space-saving mission is complete without smart storage. The principle is simple: you want to keep as much floor space free as possible.

This is partly a case of thinking vertically rather than horizontally. But it's also about buying furniture that doubles up as storage space. Examples include:

A coffee table with drawers
A fold-out writing desk
Banquette seating with drawers or inside compartments

More storage means more space. Go get some!

5. Window seats

If your conservatory is a place to sit as well as water the plants, you should consider getting ledge or banquette seating.

This creates a snug spot for you to sit and watch the garden. And if you want to entertain, you can use it instead of dining chairs.

In a small conservatory, a window seat is preferable to traditional dining furniture. You can get the dining table closer to the seating – and to the sunlight – without cluttering up the place.

6. Carefully choose your plant life

OK, so plants aren't furniture per se . But they can work with your furniture choices to save space in your conservatory.

A classic conservatory, of course, is a veritable jungle – Kew Gardens in your backyard. If your conservatory is on the small side, however, this isn't the best use of space.

A few choice plants can go a long way to help blend your conservatory with your garden and keep the space uncluttered.

7. Think vertically, not horizontally

Any big reader will tell you the importance of vertical thinking. Unless you want to spend your days wading through teetering piles of bestsellers , you'll need some stacked shelving.

The same space-saving principle can apply to conservatories. Get tall rather than wide furniture and you'll soon feel there's more room to stretch your legs.

Another example of vertical thinking is hanging plants – a far more economical use of space than sitting pots or tables.

8. Portable furniture

Want your conservatory to double up as a place for quiet time and a place to entertain? Portable furniture is the answer.

This could be as simple as a set of folding chairs or as sophisticated as a modular sofa. You could even invest in a trolley to wheel in dinner or drinks.

Other tips for maximising space in your conservatory

1. Install a skylight

Some tiled-roof conservatories have built-in skylights. This brings more light through the roof. Combined with lightweight furniture that doesn't block the windows and judiciously placed mirrors, a skylight can help create the illusion of space.

2. Opt for a lighter colour scheme

It's a guiding principle of interior design that smaller spaces go best with light colour schemes. This helps light bounce around rather than get sucked into dark surfaces. Colours like beige, off-white, sky blue and cream are your space-saving friends.

That doesn't mean, of course, that your conservatory has to beige in the pejorative sense of the word. You can still add a burst of pizzazz with a brightly coloured vase, rug, lamp or bunch of flowers.

3. Get space-saving doors

In a small conservatory, thin frames and sliding or folding doors are best. Alongside smart storage and vertical thinking, your choice of door is crucial to keeping the place uncluttered.

Final thoughts

Having a small conservatory doesn't have to be a problem. With well-chosen furniture carefully arranged, you can enjoy those garden views in comfort.

How to measure for internal doors

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 07 Jul 2025 08:07:32 GMT

Looking to install a new internal door in your home? Get the lowdown on how to measure it accurately.

Getting excited about doors, some might say, is like getting excited about traffic lights, bin bags or the history of gravel.

Well, we beg to differ. Yes, a door's main job is to open and close. But a door can add character to your home, breathe life into a room and reflect your personality.

So, if you're replacing a door, it's always worth giving some thought to the style, colour and accessories you want. Before you do, however, you're going to need some measurements.

Once you know how to do it, measuring a door is as easy as pie. But it's not immediately obvious where to start. This is primarily because a door can be measured on its own, with its jamb (side posts) or as a rough opening (the rectangle cut into the wall).

The measurement you take will depend on whether you're buying just the door or what's known as a "pre-hung door" (a door in its jamb).

If you're buying just the door, you can take measurements from your existing door. But if you're buying a pre-hung door – or are planning on replacing the jamb – you should take measurements from the rough opening.

What do you need to measure for internal doors?

Measuring for internal doors isn't a complicated task. You just need a measuring tape, a pencil and a piece of paper. (And perhaps a cup of tea.)

Measuring the existing doors

If you're buying a door and keeping the existing jamb, you can take measurements from your existing door.

First, measure the width from one side to the other. Next, measure the height from top to bottom, keeping the measuring tape inside the frame. Finally, place the measuring tape at the edge of the door and record the thickness.

For better accuracy, you can measure the width at three points, pick the smallest number and deduct 10 mm. Do the same for the height. You can also check the opening is flush by measuring diagonal lines.

Once you've got your measurements, jot them down. Note down, too, whether the hinges are on the left or right when you face the front of the door and whether it opens inwards or outwards. This is all useful information for a door supplier or installer.

Measuring the rough opening

If you're buying a pre-hung internal door, you can take your measurements from the rough opening. As with your existing door, you want to measure width, height and depth and record these measurements along with the direction the door opens and the side the hinges are on.

How to measure a front door

Measuring a front door is much the same as measuring an internal door. You need a tape measure, a pencil and some paper. Measure width, height and depth and note down whether the door opens inward or outward and whether the hinges are on the left or right.

Tips to ensure accurate measurements

There are two main ways you can ensure that your measurements are accurate. The first is to take multiple measurements and record the average. Some people recommend recording the smallest of the measurements minus 10 mm to allow for wiggle room.

Secondly, you should check and check again. To err is human. To ensure you get the right-sized door and don't waste time on returns and refunds, double- and triple-check your measurements before placing your order.

What door hinges does my internal door need?

The simple answer is that it depends. Some hinges are suitable for both internal and external doors, while others only work with one or the other. The type of hinge will also depend on the door material and how much it weighs.

If you want to find out more, check out our guide to choosing the right door hinges .

What are the differences between internal and external doors?

There are three main differences between internal and external doors. These primarily relate to the fact that external doors are outward-facing.

First of all, external doors have to withstand the elements. To do so, they usually have insulated cores, whereas internal doors are usually hollow. This is one reason why external doors tend to be more expensive.

This also affects the materials used. External doors are often made of composite materials for added strength, whereas internal doors can be made from a single material.

Thirdly and finally, internal and external doors tend to have different appearances. Both can be ornate, of course. But external doors – especially front doors – tend to draw attention and be more ornamental. Internal doors, by contrast, are more purely functional and tend to be on the plainer side.

What should you look for in an internal door?

When looking for an internal door, you should first check that the door is built to last. This will be reflected in the quality of the materials and the length of the warranty on offer. You want your internal door to be an investment – not something that needs to be replaced in a matter of years.

Related to this is the door's energy efficiency and security. A sturdy, good-quality, built-to-last door will put paid to draughts and keep intruders out. Energy efficiency is good for the planet, too, reducing your carbon emissions at the same time as your energy bills.

But perhaps the most important consideration when looking for an internal door is your choice of supplier. Working with an experienced, friendly, professional supplier can mean the difference between a smooth installation and a month of headaches.

How to clean conservatory roof glass

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 30 Jun 2025 13:11:29 GMT

Got a glass conservatory roof and wondering how to keep it clean? Join us for handy tips and tricks.

Ever sat upstairs on a double-decker bus and seen the top of a bus shelter? Many of them are miniature landfill sites heaving with leaves, moss, bird droppings and other detritus.

We hate to be the ones to break it to you – but if you invest in a glass conservatory roof, its pristine surface might start to look like one of those grimy bus shelters.

Like all outdoor furniture and structures, conservatories are vulnerable to grime from above. Twigs, leaves and other debris get blown by the wind onto the roof or block the gutters. Moss and algae thrive in the damp. Glass discolours in the Great British weather.

And it's not just that these dreary deposits make your conservatory look bad. Over time, they can lead to water pooling, ingress and leaks, too.

So, what's to be done? The answer is, of course, to give your glass roof a clean. But unlike cleaning your conservatory windows or running a Hoover around the interior, it's not immediately obvious how .

Well, before we get into the "how", let's think about the "when". How often, you may be wondering, should a glass conservatory roof be cleaned?

How often should I clean my glass conservatory roof?

Some aspects of conservatory maintenance can be done little and often: wiping down window frames and sills, say, or freshening up the furniture.

Cleaning a conservatory roof takes a bit more effort. It's not something many people are doing once a week or even once a month.

There's no right or wrong answer. It partly depends on where your conservatory is located. A conservatory under a shady bough, for instance, will need more regular cleaning than one with nothing but sky above.

You could do it once every few months or twice a year. If you go for the second option, you might want to undertake the task in spring or autumn to avoid weather-based woes.

So, while there's no scientific answer to the question, common sense tells us you should clean your conservatory roof at least once a year. This will keep it looking good, increase its longevity and make it more energy-efficient. After all, the more sunlight that gets through, the less you have to spend on artificial lighting.

What do you need to clean a glass conservatory roof?

When it comes to cleaning a glass roof, mildness is key. Harsh chemicals and abrasive tools are a no-no. They can lead to scratches and other kinds of damage.

Instead, you want to use a mild detergent or, if you prefer, a specialised glass cleaner. This can be applied with an extension pool to reach those tricky spots.

Before you apply the detergent, however, you should use a soft-bristled brush or broom to loosen up the gathering muck.

If mildness is a key priority, so too is safety. First and foremost, you should not climb onto the roof. Conservatories aren't built for walking on – and you're only putting yourself (and your conservatory) at risk.

Instead, use a ladder. If working alone, you could use a safety harness. But whether you're going solo or working with a maintenance buddy, you should wear non-slip shoes, gloves and eye protection.

And before you start climbing the rungs, make sure the weather is suitable. A wet and windy cleaning session will only sour your mood and reduce your chances of doing a good job!

How do I remove algae from a glass conservatory roof?

Algae on a glass roof isn't just an eyesore. It can also make your conservatory less energy-efficient by reducing the amount of sunlight getting through.

To remove it, you should follow the method we outlined for cleaning the roof, making sure to rinse the roof with clean water.

If the problem is persistent, you may want to invest in specialist algae cleaning solution.

What is self-cleaning glass?

These days, some conservatories use self-cleaning glass. This is a type of glass with a special coating that prevents the buildup of dirt, grime and water discolouration.

Its photocatalytic coating means it's most effective when exposed to sunlight. It can, however, still work in the shade or under artificial light.

It's important to note that "self-cleaning" is, if not a misnomer, then at least a little misleading. You will still need to manually clean your conservatory roof – just less often and with less elbow grease.

Should I pressure-wash my conservatory roof?

It's unwise to pressure-wash a glass conservatory roof for two reasons.

First, it can damage the glass. Secondly, water sprayed at high pressure can penetrate seals and joints, leading to leaks and all their attendant problems. Instead of pressure washing, use mild detergent and a soft-bristled brush.

How do you clean a polycarbonate conservatory roof?

If you have a polycarbonate conservatory roof, the cleaning method is much the same as for glass conservatory roofs. You need mild detergent and a non-abrasive cloth or brush. You then need to rinse the roof with clean water.

Should I hire a professional to clean my conservatory roof glass?

Most of the time, cleaning your conservatory roof is a DIY job. You just need the right equipment and a bit of patience. In some cases, however, it's best to get a professional in.

This applies if the roof is especially hard to access, if there's structural damage or if there's a significant buildup of algae or moss. In these instances, a DIY job may be more trouble than it's worth.

What is SupaLite?

At Calder Windows, we offer an alternative to conservatory roof glass. It's called "SupaLite" and it's a tiled conservatory roof system that's a piece of cake to maintain.

It's built to last, comes in a range of appealing colours and will keep your conservatory at a pleasant temperature from January to December. It can even increase the value of your home because it effectively creates a brand-new living space to enjoy.

A guide to uPVC stable doors

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 16 Jun 2025 11:44:40 GMT

Learn all you need to know about uPVC stable doors – from energy efficiency to maintenance requirements.

Have you got your eye on a stable door? Do you love the style but aren't sure of the benefits?

Look no further. In five minutes, you'll learn everything you need to know about stable doors – including their history, their perks and why uPVC is best.

Let's dive in.

A short history of stable doors

Stable doors (or 'Dutch doors', as they are sometimes known) have a long history of practical use on farmhouses, stables and barns. The style originated in Northern Europe and dates back as far as the 17th century.

The practical design of the stable door, with its central divide, meant agricultural workers could keep livestock safely in (or out of) an area. At the same time, it allowed for access to sunlight and ventilation.

Over time, the practical benefits of stable doors combined with their unmistakable country charm led to a huge rise in their popularity throughout Europe.

Nowadays, stable doors can be found anywhere from rural cottages to contemporary townhouses. They've truly won us over with their unique blend of style and practicality.

What makes stable doors different?

Looking for versatility? You've found it.

With both the top and bottom sections of the door secured together, a stable door acts much the same as a conventional door. However, if you lock the lower section of the door, the top half can be opened independently. This creates an effective barrier while allowing for floods of sunlight and fresh air to flow into your home.

This feature makes stable doors an attractive option for all sorts of homeowners:

Those with young children or pets
Those looking to increase ventilation in their homes
Those who enjoy feeling closely connected to outdoor spaces
Anyone who wants to add a little character to their home

What are the main benefits of stable doors?

Our top pick: unhindered sunlight and ventilation.

As we've seen, the clever design of the stable door allows the top and bottom sections to be manipulated independently of one another. This means you can keep children and young pets inside while still enjoying plenty of sunlight and fresh air.

The benefits of natural light and ventilation should not be underestimated.

Exposure to sunlight helps the body produce vitamin D and has been linked to an increased endorphins and serotonin. Not only that, but it can also help regulate your circadian rhythm – the bodily ebb and flow that governs our sleeping patterns.

Improving ventilation, meanwhile, is one of the best things you can do to prevent damp and mould. The increased airflow reduces condensation and the potential for moisture damage. It also improves air quality, removes odours and can help regulate indoor temperatures on warmer days.

Why choose uPVC stable doors?

Known for its durability and energy efficiency, uPVC has been a game-changer in the world of windows and doors.

See, stable doors were originally crafted from wood. However, while sturdy, this material can warp, rot and eventually become unsightly if not properly maintained.

However, a uPVC stable door from Calder Windows will stand the test of time – no matter what the weather throws at it.

With unwavering weather resistance, excellent energy efficiency and minimal maintenance requirements, uPVC is a hard option to beat for any new door installation. And they don't skimp on style, either. With many colour, style and glazing options available, our uPVC stable doors are delightfully customisable.

Is a uPVC stable door the right choice for my home?

It's easy to be sold on the aesthetic appeal of a uPVC stable door. However, its dual-opening function may or may not suit your home depending on your family's specific needs and preferences.

Let's take a look at some of the most frequently asked questions on uPVC stable doors. We hope this helps you decide whether they're the right choice for you.

Are uPVC stable doors secure?

uPVC stable doors are great for keeping young children and small pets indoors – and they do a good job at keeping unwelcome visitors out, too.

uPVC is a lightweight but strong material that can withstand even the most determined trespasser. This ensures an effective barrier against any forced entries, keeping your home the safe haven that it should be.

What's more, all uPVC doors from Calder Windows come fitted with top-quality Yale locks. And thanks to the weather-resistant properties and long-lasting nature of the material, your stable door should stay sound for many years to come.

Are uPVC stable doors energy efficient?

Our uPVC stable doors are built to keep warm air in and cool air out (unless you open the top half, of course).

uPVC's low thermal conductivity and tightly sealed frames help prevent heat loss. This means your rooms stay warm and comfortable on cooler days, saving you money on your heating bills and reducing your home's overall energy consumption.

Do uPVC stable doors require a lot of maintenance?

Thanks to its natural weather resistance and smooth finish, uPVC is a wonderfully low-maintenance material for your stable doors.

Unlike wood and metal, uPVC doesn't require staining, painting or sanding – and it isn't susceptible to rot or rust. A simple wipe-down with soapy water is all you need to keep your stable door looking and working as good as new.

How durable are uPVC stable doors?

uPVC is an excellent material choice for your stable doors because it's tough and hard-wearing. Being thoroughly weather resistant, your stable door won't rot, rust, warp or crack – no matter what the climate throws at it.

This means you can expect it to last many years, even when faced with harsh weather conditions and regular use. And, even better, it demands minimal maintenance and minimal fuss. Win-win!

Which are the best energy-efficient windows?

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 09 Jun 2025 08:14:17 GMT

Save money and energy with our guide to the most energy-efficient window options for homeowners in 2025.

Everybody wants to know that their home is as energy-efficient as possible. But where should you start?

Our advice: start with your windows. See, old and inefficient windows can lead to significant heat loss – as much as 30% in some cases.

With well-built, properly installed windows, you can not only lower carbon emissions but also save money on heating and cooling bills. What's more, you'll reduce noise pollution, minimise draughts and improve indoor air quality by reducing condensation.

Put simply, it's a no-brainer.

But with so many options on the market, how do you know which windows are the best for energy efficiency?

It comes down to several factors. The type of glazing used generally has the biggest impact on a window's energy efficiency. However, the framing materials used and the style of the window also play important roles.

To help us assess the energy efficiency of different window components, we'll need to look at their U-values.

U-values in a nutshell

U-value is the standard measure of thermal efficiency for building materials and elements.

U-values are given in watts per square meter per degree Kelvin (W/m²K). That's a bit of a mouthful – but it basically means 'how quickly heat is transferred'. Or, to put it even more simply, the lower the U-value, the more energy-efficient a building element is.

So, let's take a look at the different window options, their U-values and how they might compare in terms of energy efficiency.

Glazing types

Single glazing

Single glazing consists of just one pane of glass – usually between four and six millimetres thick. While it was once the standard in UK homes, single glazing is now mostly found in older or listed properties.

Single glazing typically has a U-value of around 4.8 to 5.8 W/(m²K). This is considerably higher than the new FHS requirements: 1.2 W/m²K or lower for new builds.

While single glazing is generally the cheapest glazing option, it offers poor energy efficiency. It has the highest U-value of all glazing types and loses heat about twice as quickly as standard double glazing.

Double glazing

Double glazing is now the most common glazing type in UK homes. It uses two panes of glass with an air- or gas-filled insulating cavity in between.

Double glazing's U-value generally ranges from 1.2 to 3.0 W/m²K. Even the higher end of these ratings already offers much better energy efficiency than single glazing. However, the type of glass used, the cavity width and the gas used to fill it can all affect your double glazing's U-value.

Specially coated low-E glass panels with an argon-filled cavity offer the best performance. These types of double-glazed windows boast a U-value of around 1.2 to 1.5 W/m²K.

Triple glazing

Triple glazing is fast becoming a popular choice for windows across the UK and Europe thanks to its excellent insulating properties.

Using three panes of glass with two insulating cavities, triple glazing typically has a U-value ranging from 0.8 to 1.6 W/m²K. However, high-performance triple-glazed windows can achieve ratings of 0.8 W/m²K or lower.

With such a low U-value, you can expect excellent energy efficiency, reduced heating bills and a smaller carbon footprint.

Framing material

Are you looking for optimal energy efficiency? It's important to consider the framing material as well as the glazing type.

Wood

Wooden frames can be a good choice for energy efficiency because wood is a good thermal insulator. When paired with a good-quality glazing option and installed properly, wooden-framed windows can achieve very low U-value ratings.

However, wooden frames are susceptible to water damage and, unlike uPVC, require a bit of maintenance. Regular cleaning, checks for damage and occasional repainting may be required to maintain their natural insulating properties.

Aluminium

While aluminium is a poor thermal insulator, modern aluminium window frames use thermal break technology. This means the frames include a non-conductive material (such as resin), which increases their insulating properties.

When installed alongside quality glazing, aluminium frames can be a highly energy-efficient option. They're also very durable and long-lasting.

uPVC

The most popular framing material in the UK is uPVC . Its affordability, low maintenance requirements and excellent thermal performance make it a good all-rounder for windows and doors.

UPVC is a poor conductor of heat, meaning the warmer air inside your home isn't easily transferred through the window. And on hot summer days, they'll help keep warm air out. Double-glazed windows with uPVC frames regularly achieve a U-value as low as 2 W/m²K.

What's more, uPVC frames are crafted to fit snugly against the wall, ensuring a tight seal and preventing draughts or leaks around the window. This further enhances their energy efficiency.

Window designs

While the materials used have the greatest impact on your windows' energy efficiency, the window design can also play a role.

Sash vs casement windows

Sash windows rose to fame during the Georgian and Victorian eras. Today, as then, they're loved for their elegant design and excellent ventilation.

However, casement windows are now the most popular choice for windows in the UK – especially in new builds. That's because they offer versatility, ease of operation and enhanced security. Sash windows, however, remain a close runner-up.

Sash windows

While older sash windows were typically single-glazed and could be draughty, new technology and manufacturing techniques have changed all that. Modern sash windows can be both beautiful and well-insulated.

An old single-glazed sash window may have a U-value of around 5.8 W/m²K. However, a new double- or triple-glazed sash can achieve a U-value of 1.2 W/m²K or lower.

Casement windows

Modern casement windows use a compression seal that can create a more airtight seal than a traditional sliding sash. When paired with top-quality glazing, a casement window's U-value can reach 1 W/m²K or lower.

Thanks to their simple opening and locking mechanisms, casement windows are also very wear-resistant. They can keep your home insulated for many years with minimal upkeep.

Casement windows generally offer slightly better energy efficiency than sash windows. However, the difference can be minimal – as long as they're crafted and installed by reputable companies.

The takeaway

If you're looking for the most energy-efficient windows – with the lowest U-value and best insulating qualities – triple glazing is the way to go.

When combined with high-quality frames and a skilled installation, triple glazing could deliver a U-value as low as 0.8 W/m²K – or even lower. For you, this means saving money on your energy bills and reducing your home's carbon footprint all at once.

Are skylights a good idea?

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 02 Jun 2025 08:15:32 GMT

Skylights can be beautiful as well as practical – but are they right for you? Let's weigh up the pros and cons.

When planning a home renovation or designing a new build, few features offer the transformative effect of a well-placed skylight.

Skylights can open up a space, flood it with natural light, and add architectural interest to otherwise plain ceilings. But as with any design decision, skylights come with both benefits and potential limitations.

So, are skylights a good idea? The short answer is "yes". For many homeowners, skylights can be an excellent addition, improving aesthetics, comfort and even property value. However, they are not a one-size-fits-all solution.

In this article, we explore the pros and cons of skylights, when they work best, and how our expert skylight installers can help you reap the benefits.

The benefits of skylights

1. Natural light and health benefits

One of the most compelling reasons to install a skylight is the increase in natural light. Unlike vertical windows, skylights allow sunlight to enter from above, providing more even illumination throughout the day. This has both practical and psychological benefits.

Numerous studies have shown that exposure to natural light improves mood, boosts productivity and helps regulate sleep cycles. In rooms where wall space for windows is limited – such as bathrooms, hallways or attic conversions – a skylight can be the perfect solution.

2. Energy efficiency and cost savings

A properly installed and energy-efficient skylight can reduce the need for artificial lighting, particularly in darker months. Calder Windows offers skylights with advanced thermal insulation, helping to minimise heat loss in the winter and reduce heat gain in the summer.

Ventilated skylights also help regulate indoor temperature by allowing hot air to escape. This can result in lower energy bills and a smaller environmental footprint over time.

3. Aesthetic value

A skylight can dramatically enhance the visual appeal of a room. It can turn a cramped loft conversion into a cosy, light-filled retreat, or add a sense of openness to kitchens and living areas. The play of light and shadow from above adds architectural drama, especially in spaces with vaulted or sloped ceilings.

Calder Windows' wide range of skylights, including roof lanterns and flat rooflights, offers flexibility in design, helping homeowners achieve the exact look and function they desire.

4. Improved ventilation

Many modern skylights are operable, meaning they can be opened to allow fresh air to circulate. This is especially beneficial in humid areas like kitchens and bathrooms where moisture can accumulate. A skylight placed at a high point of a ceiling can act like a chimney, drawing warm, moist air upwards and out – a principle known as stack ventilation.

5. Increased property value

Natural light and attractive interior spaces are high on many buyers' wish lists. A well-installed skylight can make a home feel more inviting and spacious. As such, it may increase the perceived – and actual – value of a property. Features that improve sustainability and energy efficiency, like the skylights offered by Calder Windows, are particularly appealing in today's eco-conscious housing market.

Potential drawbacks of skylights

Despite their advantages, skylights are not suitable for every home or situation. It's important to be aware of potential downsides before making a decision.

1. Installation complexity

Installing a skylight involves cutting into the roof, which must be done with precision to avoid structural damage, leaks or insulation issues.

Poor installation can result in water ingress, mould growth or heat loss. That's why it's crucial to work with experienced professionals like Calder Windows. With more than 30 years of experience under our belts, we ensure installations are compliant with all building codes and manufacturer specifications.

2. Risk of leaks

One of the most common concerns homeowners have about skylights is the potential for leaks. This risk increases if the skylight is improperly installed or if the flashing (the waterproof barrier between the skylight and the roof) fails over time.

However, modern skylights are designed with advanced sealing systems and weather-resistant materials to drastically reduce this risk. With a high-quality skylight from a trusted installer, leaks should never be an issue.

3. Privacy concerns

While skylights are located on the roof and generally out of view, there may still be privacy concerns in densely built urban areas or multi-story dwellings. Some homeowners may feel exposed, especially in bathrooms or bedrooms.

In such cases, frosted glass or skylight blinds can offer a solution. Skylight blinds are typically made to measure and are operated manually (with a long-handle tool) or electronically (with a remote control).

4. Cost

Skylights tend to be more expensive than traditional windows, not just in terms of materials but also due to the specialised labour required for installation. While basic models are affordable, high-end, motorised, or custom skylights can be a significant investment.

However, when viewed as a long-term value-add – improving energy efficiency, aesthetics, and property value – the cost can be justified.

Here at Calder Windows, we work hard to keep our skylight installation costs affordable while delivering the very best in performance and aesthetics.

Conclusion: skylights are a bright idea – with the right installer on your side

Skylights can offer remarkable benefits—more natural light, improved ventilation, reduced energy bills and enhanced aesthetic appeal. When designed and installed correctly, they can add beauty, comfort and value to any home.

However, they are not without their challenges. Issues can arise if the skylight is poorly placed or installed. That's why it's essential to work with reputable providers like Calder Windows. We offer expertly designed products, professional installation and a 10-year warranty as standard.

So, are skylights a good idea? Absolutely – provided they are chosen with care and installed by trusted experts. With a trusted installer guiding the process, skylights can be one of the most rewarding upgrades you can make to your home.

What is a roof light?

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 02 Jun 2025 07:58:55 GMT

What is a roof light – and do you need one? Discover more about roof lights and the different styles available.

Roof lights are great. As well as acting as the focal point of a space, roof lights flood the room with daylight. And with designs to suit every taste and budget, it's never been easier to reap their benefits.

But we know what you're thinking – what is a roof light, exactly? Is it the same as a skylight? Or a loft window? Who came up with all these names?

Let's start by clearing up this common source of confusion.

Is there a difference between a roof light and a skylight?

In short, yes – but it's not that big of a fuss.

In the spirit of the "po-tay-toe, pot-ah-toe" debate, the term "skylight" is typically used for angled installations. It can also be used for flat-roof styles – though the appearance does tend to change dramatically depending on the application.

Even so, any term is OK to use. "Roof window", "roof light", "skylight" and "loft window" are equally common. Sure, there are a few subtle differences between them. But unless you're making an enquiry to a specialist, these terms are recognisable enough that you won't have to worry about which is technically correct.

Types of roof lights

Roof lights come in several styles. Beyond aesthetics, there are benefits specific to each style, as well as important considerations around installing and using their features.

Here's a quick guide to the different types of common roof lights.

Flat roof lights

As the name suggests, these units typically sit flush to a level roof space, using a kerb system to ensure water doesn't pool on the glass.

This type of roof light is available in a variety of designs to bring light and style, regardless of room or home size. It's usually sealed, making it ideal for bringing natural light to spaces where ventilation isn't a priority (think hallways, corridors and corner spaces).

It's also possible to host flat window lights on pitched roofs. These are most common in attic bedrooms.

Framed and frameless window styles

Flat roof lights often come with the option of having a visible or integrated frame. These are, respectively, known as "framed" or "frameless" designs.

Expansion of natural light is celebrated in frameless designs, where the illusion of a pure-glass ceiling offers a touch of modern elegance. By contrast, framed window lights offer striking statement lines, providing extra depth to the feature.

Both choices are ideal for large home spaces where the light is both functional and transformative. Examples include living and dining areas.

Opening roof lights

These roof lights open and close like a horizontal window. This is the style most will think of when picturing roof window lights.

These adjustable units are an excellent solution for places where air circulation is essential, such as bathrooms and kitchens. The mechanism can be manual or automatic, depending on the user's needs – and how hard it is to reach.

Walkable roof lights

Are you planning to use your roof as an outdoor space? If you're including a roof light, it's vital that the structure is sturdy enough to walk on.

This is not a design style in and of itself. However, it's hugely important to select the right materials for the purpose. That's why companies often sell pre-built options as "walk-on roof lights" or "walkable roof lights".

Pyramid or lantern ceiling lights

These types rise up from the roof space, where multiple panes taper into points.

Commonly found in museums, libraries and orangeries, this style is all about grandeur – a far cry from the modern chic offered by seamless flat styles.

The number of bars tends to impact the end result. A rule of thumb is that the panes will need at least three bars to support the angled structure. At that number, they will still maximise light – but with a design subtle enough that it won't cause distraction in a minimalist home.

What are the benefits of roof lights?

Roof lights allow a significant amount of natural light into the room, instantly creating a brighter and more inviting environment. Through careful positioning, this sleek feature can successfully elevate dark corners, invite the outside world in, and guide the eye through the space.

Beyond making an architectural statement, good-quality window installations tend to be low-maintenance and highly energy-efficient. High-quality installations carry a long lifespan, so be sure to choose reputable providers that offer generous warranties and aftercare.

With the proper installation management, roof lights can enhance the home and add long-term value to the property price. With plenty of sizes, shapes, designs and price options, it won't be difficult to find inspiration for your space.

Roof light installation considerations

When planning a roof light for your home, be sure to think about:

Purpose and placement: what do you want to achieve with your roof light?
Glazing options: for example, do you need thermal or UV coatings?
Quality of materials: because here in the UK, we get every type of weather!
Ease of installation: you want a trouble-free installation that's simple to maintain.
Style: do you want an eye-catching statement or a subtle feature?

Are roof lights a security risk?

As with any window in the home, roof and skylights do provide another entry point for sneaky intruders. It's not a cause for concern, though – most good ceiling windows will come with secure locking mechanisms.

At Calder Windows, we believe the security of our clients isn't just a nice-to-have – it's vital. We never cut corners and only ever work with trusted, high-quality suppliers for our lockable components.

Do I need planning permission for a roof light?

Permission is not generally required for roof lights or lanterns – provided they don't exceed rules on projection, height and glazing.

Homeowners should check with their local council, seek technical guidance on the government planning portal and engage the expertise of a professional installer.

Some roof lights can be bought as DIY packs. But with a qualified installer, you'll make sure your dazzling new feature lasts as long as possible.

Why choose uPVC fascias and soffits?

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 19 May 2025 09:55:10 GMT

Time to give your roofline a new lease of life? Discover the many benefits of uPVC soffits and fascias.

When undertaking a home renovation, especially one involving the roofline, many homeowners are faced with decisions about which materials to use for soffits and fascias.

These components, although often overlooked, play a vital role in the structure and functionality of a home – as well as its kerb appeal.

Among the various material options available, unplasticised polyvinyl chloride (uPVC) has become increasingly popular – and for good reason. uPVC soffits and fascias offer many benefits, from low maintenance and cost-effectiveness to durability and aesthetic versatility.

This article explores why uPVC is a smart choice for anyone looking to upgrade or replace their roofline.

What are soffits and fascias?

Before delving into the benefits of uPVC, let's cover the basics. What are soffits and fascias – and why do they matter?

Fascias are the long, straight boards that run along the lower edge of the roof, covering the ends of the roof rafters. They support the bottom row of tiles and provide a fixing point for gutters.
Soffits are located underneath the fascias, bridging the gap between the wall and the roof edge. They help ventilate the attic and protect rafters from the elements.

Together, these elements protect the roof and interior of the home from weather damage, pests and rot while contributing to the overall look of the property.

9 benefits of uPVC fascias and soffits

1. Low maintenance

One of the most appealing benefits of uPVC soffits and fascias is their easy upkeep.

Unlike wood, which requires regular painting, sealing or varnishing to prevent rot and decay, uPVC requires no special treatment. It doesn't absorb moisture, so it won't swell, warp or crack.

It's delightfully easy to keep clean, too. Routine cleaning with a cloth and soapy water is usually enough to keep uPVC components looking their best.

This ease of maintenance saves homeowners both time and money in the long run. Over a span of years, the minimal upkeep required makes uPVC a cost-effective and hassle-free solution.

2. Durability

uPVC is highly durable and resistant to the common issues that affect materials like wood. It's not prone to rotting, warping or insect infestation, making it ideal for rooflines where constant exposure to the elements is a given.

The lifespan of uPVC soffits and fascias typically ranges from 20 to 40 years, depending on the quality of the product and local weather conditions. This long life means fewer replacements over time, making uPVC a reliable long-term investment.

3. Weather resistance

Homes in the UK, where the weather is unpredictable at best, can particularly benefit from uPVC. The material is resistant to heavy rain, snow, UV rays and fluctuating temperatures. It never rusts or corrodes – and it maintains its structural integrity in both hot and cold climates.

This resistance to weathering means that uPVC soffits and fascias provide consistent protection to the structure of your home. They're a trusty ally in the battle against water ingress and damp – both of which can be costly to repair.

4. Aesthetic appeal

Modern uPVC soffits and fascias are available in a wide variety of styles, colours and finishes. This gives you the freedom to tailor the look to match the rest of your property.

Perhaps you'd like a classic white finish, Maybe you'd prefer a woodgrain effect that mimics traditional timber. Good news, either way: uPVC can accommodate both contemporary and traditional tastes.

Moreover, the clean, sharp lines of uPVC components contribute to a neat and polished appearance, enhancing kerb appeal and potentially increasing property value.

5. Cost-effectiveness

Compared to wood and aluminium, uPVC is generally more affordable – both in terms of material cost and installation. It's lightweight, so it's easier and quicker to install (which means lower labour costs). And because it requires little to no maintenance, there are minimal ongoing expenses.

For homeowners working to a tight budget, uPVC offers an ideal balance between upfront affordability and long-term value.

6. Easy installation

As mentioned, uPVC is lighter and more manageable than many alternative materials, which simplifies the installation process. Many uPVC soffits and fascias come in pre-formed panels and interlocking systems that allow for seamless fitting.

This ease of installation ensures that the renovation project can be completed more swiftly than if using heavier, more labour-intensive materials like hardwood. For you, this means less disruption, less noise and fewer snags to worry about.

7. Sustainability

Plastic is bad for the environment, right? Well, uPVC is more sustainable than you might think.

For a start, it's recyclable. Very recyclable. uPVC can be recycled 10 times or more without impacting quality or performance.

Additionally, because it lasts so long and requires fewer replacements and less maintenance, uPVC contributes to resource conservation and waste reduction over its lifecycle.

That said, many uPVC products still end up in landfill – despite their recyclability. When the time comes (eventually) to replace your soffits and fascias, we recommend making sure they're disposed of responsibly.

8. Improved ventilation

Modern uPVC soffit systems often include integrated ventilation slots, which allow air to circulate within the roof space. This is crucial for preventing condensation build-up. Too much condensation, you see, can lead to mould, damp and rot in the attic.

By facilitating proper airflow, ventilated soffits help maintain a healthy roof environment, reducing the likelihood of moisture-related structural problems.

9. Pest deterrence

Wooden roofline components can attract pests such as birds, wasps and insects, which may find nesting sites in decaying or unsealed areas. uPVC, being non-organic and tightly fitted, offers no such opportunities. It provides a clean, sealed surface that deters pest entry and nesting.

Keeping unwanted critters out of the roofline not only protects the home but also spares residents the nuisance and potential damage caused by infestations.

Final thoughts

Renovating a home is a major undertaking – and choosing the right materials for every component is essential to ensure longevity, performance and return on investment. When it comes to soffits and fascias, uPVC stands out as a superior option for many reasons.

From its low maintenance and long lifespan to its cost-effectiveness and aesthetic flexibility, uPVC offers a practical and attractive solution for homeowners like you. Its resistance to weather and pests makes it particularly suited to the demands of today's homes, while its ease of installation and upkeep ensures peace of mind for years to come.

For anyone planning a renovation, especially one involving exterior or roofline work, uPVC soffits and fascias represent a smart, future-proof choice that blends durability with design appeal.

How triple glazing works

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 12 May 2025 16:45:42 GMT

What is triple glazing, how does it work and is it worth it? Get all the answers in our consumer guide.

A change is taking place in UK homes. Triple glazing is replacing double glazing as the standard for new-build homes across the country.

This is partly thanks to new building regulations, rising energy costs and government policies aimed at reducing emissions. But savvy homeowners are driving this development, too.

Yes – more and more people are getting wise to the benefits of triple-glazed windows. Their energy-saving properties. Their soundproofing benefits. Their increased security…. The list goes on.

But if you're new to triple glazing, you probably have questions. Questions like, "What is triple glazing, anyway?" and, "How does it all work?"

Fear not – we've got you covered. Let's jump in with the basics.

How triple glazing works

Triple glazing takes the science behind double glazing and builds upon it. Instead of using two panes of glass per unit, triple glazing uses three – each separated by a sealed gap filled with an insulating gas.

That extra pane of glass and insulating space help reduce heat and noise transfer from the exterior to the interior – and vice versa.

What are the advantages of triple glazing?

The design of our state-of-the-art triple-glazing units means your home could be reaping their benefits today, tomorrow and for many years to come.

The superior insulating properties of triple glazing can lead to an overall more comfortable living environment for you and your family. You can expect more consistent temperatures throughout the home, reduced draughts and even improved air quality. That's because triple glazing helps reduce the risk of damp.

And better insulation means more energy savings. This is good for the planet and your pocket.

Why? Because your home will be warmer and more comfortable. You'll be less likely to reach for the thermostat, which means cheaper energy bills in the long run.

Triple glazing FAQs

Will triple glazing reduce condensation in the home?

Yes! Triple glazing is an effective way to reduce reducing condensation in the home.

Condensation occurs when the warm, humid air inside your home comes into contact with the cooler surface of your window. This temperature change causes the water vapour inside the air to condense and form water droplets on and around your windows. If left untreated, this moisture can cause damp, mould and mildew.

Many UK homes battle against condensation, damp and mould – mainly thanks to our infamous weather. Older single-paned or insufficiently sealed double-glazed windows can increase your home's chances of excess condensation. Condensation, in turn, can lead to poorer air quality, potential health risks and possible structural damage.

The additional pane of glass in triple glazing offers better insulating properties than single- or double-glazed windows. In addition, gases with low thermal conductivity, such as argon or krypton, are used in the two insulating layers between the panes.

These gases minimise heat transfer, keeping the internal glass pane warmer and therefore less likely to reach the dew point – the temperature at which condensation occurs.

Pair this with water-resistant, airtight framing materials like uPVC or aluminium and you've got an effective solution for staving off condensation.

How does triple glazing reduce noise pollution?

You know how triple glazing's superior insulating properties can reduce condensation? Well, they can also help reduce excess noise pollution entering your home. Bonus!

Glass panes, although excellent for letting in sunlight, are fairly poor sound absorbers. They easily vibrate when hit by sound waves, which then pass through into your home.

Stuck with single glazing or poor-quality double glazing? This poor sound absorption is why noisy traffic or a garden strimmer can sound more like it's in your living room than outside.

It's not just the glass panes that let in the sound, either. Poorly sealed windows, or any gaps and cracks in the frames, can also allow noise to enter.

Triple glazing's extra insulating spaces make a big difference – as does its gas filling, which is denser than air. This combination helps to absorb and dampen sound waves travelling through the window. It also helps to reduce the amplitude and energy of the waves, further lessening the intensity of the sound.

Could triple glazing reduce my energy bills?

Triple glazing makes for an excellent investment thanks to its low U-value.

A U-value of a window measures how fast heat can travel through it. Most double glazing has a U-value of around 1.6W/m²K. Our triple-glazing units, however, offer a U-value of around 0.7W/m²K and achieve the best possible rating on the BFRC energy-efficiency scale. Installing our triple glazing can boost the thermal efficiency of your windows by up to 40%.

What this means is that your house stays warm in winter and cool in summer. It's the best of all worlds – a more comfortable living space, a reduction in energy bills and a little extra help for planet Earth.

Can triple glazing increase my property value?

As energy costs rise and the public gains a better understanding of climate change, more people than ever are looking for an eco-friendly, energy-efficient home.

So, when the time comes to place your house on the market, triple glazing will certainly act as an attractive selling point.

What's more, all our windows and doors are beautifully designed and expertly fitted. This means more of that all-important kerb appeal.

Are triple-glazed windows more secure?

While well-fitted double glazing is very durable, triple glazing works even harder to prevent break-ins and deter would-be intruders.

The extra pane of glass in our triple-glazing units boosts their strength. In addition, they have super-robust frames and secure locking mechanisms. It all adds up to extra peace of mind for you and units that will stand the test of time.

What are the disadvantages of triple glazing?

By design, triple-glazed units are slightly heavier than standard double glazing. And while they make for a good investment, you can expect to pay more upfront.

Or, at least, that's how it usually works.

Replacing French doors: how to know when the time is right

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 05 May 2025 06:43:26 GMT

Got cracks or draughts? Learn the top telltale signs that it's time to replace those old French doors.

French doors are a beautiful addition to any home. They flood your room with natural light, opening up rooms and introducing seamless access to your outside space.

But like many home improvements, French doors can start to look a little worse for wear after years of enjoyment. How do you know when the time is right to change them?

Here are some telltale signs that your French doors might need replacing.

Visible damage

Visible deterioration or damage is a sure sign your French doors have seen better days.

Any cracks or chips in the glass, no matter how small, can seriously affect the integrity and safety of the door. Splits or fractures in the frame, meanwhile, could be a sign of warping or water damage.

Either problem is a strong signal that your doors need replacing – and fast.

Trouble with opening or closing

French doors that stick or scrape can sometimes be fixed by tightening the hinges. But if you have persistent difficulty opening or closing them, it may be a sign of a bigger problem.

Water damage from impaired seals or prolonged exposure to extreme temperatures and weather conditions can cause French doors to warp or bow.

Door warping is notoriously difficult to fix. It might be better to replace the doors with a fresh new set.

In any case, it's important to resolve the problem as soon as possible. If your French doors don't open and close properly, it's not just annoying – it can also lead to other, more serious issues, such as damp.

Difficulty with the handle or lock

Door locks and handles should be built to withstand regular use. A stiff handle or a lock that jams may mean the mechanics of your door are on the wane.

Sometimes, this can be a fairly simple fix – like replacing the lock. However, if the damage is due to rust from leaking seals or a "drop" in the frame, more serious intervention is needed. It might be time to look at replacing the whole unit.

Condensation or foggy glass

Have you noticed condensation buildup or a foggy appearance in the glass? It could be a sign of glazing failure.

This can happen for a number of reasons, including:

Seal deterioration
Poor installation
Thermal stress
Excessive force on the door

Not only is it unsightly, but failed glazing can also lead to excess moisture buildup, poorer insulation and increased noise pollution in your home.

Draughts

Draughty doors can be bad news. For your home, it can mean cold rooms, chilly floors and reduced thermal efficiency.

Draughts can be caused by damage to seals, frames or hinges. They might also occur if an older unit has settled significantly over time.

Effectively sealed and properly installed French doors shouldn't allow for the outside air to seep in. A noticeable draught can be a good giveaway that it might be time to look for something new.

Signs of damp around the door frame or walls

Sometimes, the signs of a tired French door don't appear on the door itself but show themselves on the walls and furnishings around it.

This is because damaged or deteriorated French doors can allow for water ingress. Dark patches on walls, rotted wood, peeling paint, and mould spots on curtains, walls and ceilings can all signal water ingress.

Insufficient insulation or sealing, leaking frames or structural warping aren't always obvious at first glance. However, it's important to address these problems quickly as they can cause a host of issues that are often harder to address than the door. Often, a new door is the simplest fix.

Rising energy bills

Your French doors may not show obvious signs of wear and tear. However, your energy bills will let you know if your home is not insulated effectively.

If you're ramping up the heating in winter or leaving the fans on through summer, it probably means something in your home isn't effectively sealed. The main culprit is likely improperly installed or worn-out windows or doors.

What to do if you've seen the signs

Seeing evidence of any of these problems with your old French doors may mean the time has come to replace them.

A modern, properly installed and well-insulated French door can save you money on your energy bills while making your home a more comfortable, consistent temperature.

Trust Calder Windows for your next French door installation . Our French doors are not only beautifully crafted but are also secure and built to last. Each comes with a 10-year warranty as standard, plus aftercare when needed for your peace of mind.

We offer a huge library of styles, colours and panes, plus the option of an integrated state-of-the-art Uniblind. So, why not upgrade your old French doors with something special from Calder Windows?

UK government grants for home improvements [2025 guide]

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 28 Apr 2025 08:10:52 GMT

Everyone deserves a warm home. Learn what government help is available when improvements are needed.

A 2024 NatWest survey revealed that a third of homeowners intended to make sustainable home improvements within the next five years.

The same survey found that 65% of the homeowners answered "yes" when asked if they intended to make sustainable home improvements within 10 years. Interestingly, out of the 35% that said "no", the majority said the cost of the work was the barrier.

The good news is that help is available. The UK government offers grants and schemes to help low-income households benefit from sustainable home improvements, whether they own or rent their homes.

In this guide, we explain how to access this support and cover the various grants available in 2025. We also look at another option: our free upgrade from double glazing to energy-efficient triple glazing .

The first step: getting an Energy Performance Certificate

Your property must have an Energy Performance Certificate (EPC) before you can check for eligibility. This is issued by an approved assessor after looking around your home.

An EPC rates your home's energy efficiency and carbon footprint. To figure this out, the assessor will look:

At your windows
At your heating and hot water systems
At your lighting
For any evidence of insulation (they will need access to your loft)

They will also take into consideration the age and construction of the building, including its dimensions, layout and number of usable rooms.

Each property receives an alphabetical rating from A down to G. An EPC rating of D or below is regarded as energy-inefficient and would be prioritised for help.

Not sure if you have an EPC? If you moved into your home after 2007, you can check the online EPC register for free.

If you're a homeowner and your property doesn't have an EPC, you'll need to pay a fee to have an assessment. Shop around online and at local estate agents, as the amounts charged can vary.

If you're renting, your landlord is legally obliged to provide an EPC – even if your home is a listed building.

What schemes and grants are available?

There are a variety of ways to get help. Let's have a look at them in detail.

Green Homes Grant

No longer active

We'll get this one out of the way first. While the Green Homes Grant still appears on Google searches, it stopped taking applications in March 2021.

Don't worry, though – there are still options available that may be suitable for you.

Support for Mortgage Interest (SMI)

Currently active with no set end date

Have you taken out a loan for home improvements but are now struggling to pay? The SMI scheme could help with paying the interest.

The SMI is a loan you must pay back with interest when you have enough equity – for example, if you sell your home. To check the full terms and conditions and eligibility criteria, see GOV.UK: https://www.gov.uk/support-for-mortgage-interest

Energy Company Obligation scheme phase 4 (ECO4)

Began in 2022 and is set to end in March 2026

This government scheme is funded by the major UK energy companies to improve the least energy-efficient homes and reduce carbon emissions with renewable energies.

This can include upgrading boilers and heating systems, providing insulation and heat pumps, and even installing solar panels.

Eligibility depends on the benefits you're claiming and your home's EPC rating. You can learn more on GOV.UK and apply from there: https://www.gov.uk/energy-company-obligation

Note: renters will need their landlord's permission for any work done.

Local Authority Flexibility scheme (LA FLEX)

An add-on to ECO4

This is for anyone:

With a low income
Who lives in a property that qualifies for ECO4
But is not claiming any qualifying benefits

You will need to contact your local authority (council) directly and ask to be assessed for the scheme.

Boiler Upgrade Scheme (BUS)

Began in April 2022 and is set to continue until March 2028

This government grant encourages replacing fossil fuel heating systems (oil, gas, electric or LPG) with low-carbon heating systems. That means heat pumps or, in specific circumstances, a biomass boiler.

The scheme will pay part of the cost of installation for you. However, you should first check if your property is eligible via GOV.UK, as there are some exclusions: https://www.gov.uk/apply-boiler-upgrade-scheme

Next, you'll need quotes for the work from MCS-certified installers. Once you accept a quote, the installer must apply for the grant for you on the Ofgem website. The amount granted will be taken off the cost, and you'll pay the rest.

BUS still requires an investment from you, but the benefit should be a warmer home with much lower energy bills.

Warm Homes: Local Grant

Began in April 2025 and is set to run for at least three years

Local authorities in England have been allocated funding by the government's Warm Homes Plan. This aims to bring five million homes to an energy-efficient grade within five years. Their agenda is to target fuel poverty and give people warmer homes with less energy costs.

The Local Grant covers properties that are privately owned – either by the occupant or a landlord – with an EPC grade of D or below. It will fully fund any allocated improvements, which can include insulation, heat pumps, smart controls and solar panels.

The eligibility for this one is quite broad, so it's definitely worth checking if you can apply: https://www.gov.uk/apply-warm-homes-local-grant

Warm Homes: Social Housing Fund

Began in April 2025 and is set to run for at least three years

This is part of the Warm Homes Plan for social housing and covers properties with an EPC grade of C and below. As with the Local Grant, its aim is to provide warmer, more energy-efficient homes.

Upgrades available include insulation, heat pumps, solar panels and double glazing. Landlords are expected to pay 50% of the cost.

Contact your social housing company if you think your home qualifies. Here's a list of eligible social housing companies .

Disabled Facilities Grants (DFG)

Introduced in 1989 and does not have a set end date

This grant is to help individuals with disabilities make essential changes to their homes so they can get around more easily and manage everyday tasks.

Adaptations to your home could include:

Wider doorways
Ramps
Grab rails
A stairlift
A walk-in shower or wet room
Improved access to your garden
An extension to make a downstairs bedroom
A more suitable heating system
Adapted controls for heating and lighting

Eligibility depends on your savings and income – unless the grant is for a child under 18. See the criteria and learn how to apply at GOV.UK: https://www.gov.uk/disabled-facilities-grants

Another option: Calder Windows' free triple-glazing upgrade

Investing in our A++ triple-glazed windows is an extremely effective way to save on energy costs and add value to your home.

And now, we're thrilled to be able to offer our customers a free upgrade to triple glazing when they place an order for double glazing.

With our revolutionary triple-glazed units, you could see a 40% improvement in the thermal efficiency of your existing windows, leading to huge savings on heating costs.

Thousands of UK windows are missing (and it's William III's fault)

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 21 Apr 2025 09:03:57 GMT

Home too dark? William III may be to blame. Learn about his window tax and how we can brighten things up.

Do you live in an older home? Have you ever been frustrated by the lack of natural light – staring at a solid wall that could have housed an extra window or two?

You're not alone – and you've got one man to blame: King William III. Your lack of light is a direct result of his sneaky little scheme, the window tax. (Unless you live in a new build, of course. Then you can pass that blame onto the developers.)

But back to William. In 1696, desperate to line the royal coffers without causing a public uproar, he introduced what seemed, at the time, like a clever tax scheme.

Income tax was wildly unpopular (nothing changes, does it?) Back then, people weren't just worried about how much they had to hand over to the government. They were also horrified at the idea of telling anyone how much they earned.

Income was private business – and they intended to keep it that way. So, William came up with a way around it. If you can't tax income, why not tax windows?

Taxing light and air

From the perspective of the Crown, it was genius. You could count windows without setting foot inside someone's home. And the wealthier the homeowner, the more windows they'd have – especially in grand country houses designed to show off their status.

So, it was, in a twisted way, progressive taxation… or, at least, that was the pitch.

The tax was split into two parts: a flat-rate house tax of two shillings per property (roughly £17.53 in today's money) and an additional fee based on how many windows you had.

Have more than 10? Pay up. Got over 20? Pay even more. And if you were lucky (or rich) enough to have over 30, the taxman was really interested in you.

Time to brick those windows up

As you can imagine, people weren't thrilled about being taxed for letting a bit of sunshine in. So, in true British fashion, they came up with a workaround: bricking up their windows.

Have you ever wandered down an old street and spotted suspiciously symmetrical bits of wall where windows should be? You may have just found evidence of a tax dodge from 300 years ago.

These bricked-up windows became a symbol of quiet rebellion. Forget storming castles or raising pitchforks. Just get some bricks and some mortar and give William III a metaphorical "get stuffed!"

Daylight robbery

It's often said that the phrase "daylight robbery" was born from the window tax, and you can see why. You're being robbed of daylight, plain and simple.

Though historians will argue about the accuracy of the phrase's origins, it's too good a story not to repeat. Whether or not it's true, it captures how people felt at the time – taxed on their right to light and fresh air. The audacity .

See, while the wealthy could afford to keep their windows (and pay the tax), some poorer households had to choose between daylight and dinner. Many chose darkness. As historian Adam Smith noted, the window tax disproportionately affected the poor and became a rallying cry for reform.

Time to label your cheese room

In 1778, the law was tweaked. The flat-rate tax was scrapped and replaced with a variable window tax depending on property size and location. Poorer households got a bit of relief.

Churches were also exempt, and in an oddly specific twist, cheese rooms were let off the hook, too. The same went for dairies and milkhouses – provided they were properly labelled.

The health crisis: darkness comes at a cost

It wasn't just a matter of dimly lit drawing rooms. Cutting out natural light came with serious health consequences.

In cramped, poorly ventilated housing, diseases like tuberculosis spread rapidly. Lack of sunlight also contributed to rickets, a disease caused by vitamin D deficiency.

Campaigners began to argue that the window tax was more than unfair – it was dangerous.

The public outcry grew until, finally, the government saw the light. On 24 July 1851, the window tax was abolished in England, Wales, Scotland and Ireland. France, however, decided to keep taxing windows until 1926.

So, what's left behind?

Thanks to the window tax, the architectural legacy of 18th- and 19th-century Britain is full of quirks. That includes bricked-up windows and homes that seem a little gloomier than they need to be.

The next time you're house hunting and wondering why it's a bit dark, it might not be the fault of your estate agent. It could just be that William III is still haunting your property.

And if you live in a home like that, we feel your pain.

Time to let the light back in

At Calder Windows, we believe you shouldn't have to live with the legacy of daylight robbery. Everyone deserves a home filled with natural light without worrying about draughts or sky-high heating bills. Whether you've inherited a house with bricked-up windows or you're just ready for a brighter space, we can help.

We install high-quality, energy-efficient windows that complement both traditional and modern homes. Our expert team can talk you through your options, whether you're after classic sash windows to suit a period property or sleek, contemporary styles to bring your home into the 21st century. And we'll make the process simple, with minimal disruption and competitive quotes.

We can't change history, but we can help you change your windows. Get in touch with Calder Windows today and find out how our window fitting services can bring a little more light into your life.

What is the best triple glazing on the market?

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 14 Apr 2025 08:30:34 GMT

Triple glazing is big news among UK homeowners. But whose is best? Hear why we think ours hits the mark.

With a market share of around 60%, triple-glazed windows are already the standard in many parts of Northern Europe and Scandinavia.

And now, the good news has reached homeowners in the UK. Thanks to its extensive list of practical and economical benefits, triple glazing is becoming more and more popular on these shores.

Improved energy efficiency, increased security and reduced noise pollution are but a few of the advantages of investing in triple glazing.

And your options won't be limited. There are plenty of triple-glazing products on the market.

But, of course, not all of them are created equally.

How can you be sure that you're investing in the best?

At Calder Windows, we truly believe our triple glazing is the best of the best.

We've spent the last 30+ years installing doors and windows in Yorkshire. We've seen many products come and go – including plenty of glazing technologies. And we can confidently say that we've never seen a product that offers such energy efficiency gains and all-around value.

"Of course", you might be thinking, "they would say that." And sure – we might be a little biased. But stick with us for a few minutes and we reckon you'll be right on board. Here's why.

What separates our triple glazing from the rest

1. We use extra-thick (and extra-efficient) triple-glazing units

Triple glazing involves using three panes of glass for each window, with two insulating gas-filled spaces in between. In essence, it does all the good things double glazing does – only better.

Most triple-glazed windows on the market today use 28mm-thick units. This is the same thickness as most forms of double glazing.

At Caldow Windows, however, we use a unit that's 43% thicker than the standard. This extra thickness creates a more effective thermal barrier, so you can expect greater gains in energy efficiency.

Not only that, but we're among the best installers in the business. Thanks to our craftsmanship and attention to detail, you'll be reaping the benefits of your triple glazing for many years to come.

2. It offers better thermal insulation

Our triple glazing offers some of the best thermal insulation you can get.

Around 18% of heat loss in the average UK home is through its windows. But with our 40mm-thick units, you could improve the thermal efficiency of your windows by a huge 40%.

And this efficiency works both ways. Our triple-glazing system will help keep your home cosy and warm through the cold winters and cool and fresh during hot summers.

The result? A more comfortable living space all year round.

3. It complies with U-value regulations – and then some

Since 2022, UK building regulations have required new builds to have a U-value of 1.2 W/m²K or lower. The government introduced these new regulations in a bid to reduce carbon emissions.

Our triple glazing would give your windows the incredibly low U-value of around 0.7 W/m²K. Not only does that more than comply with regulations, it will also help you reduce your carbon footprint – and save money while you're at it.

4. It meets the UK's highest possible energy rating

Our triple glazing is certified to the best possible energy rating of A++ on the BFRC scale.

For you, this doesn't just mean improving the look and feel of your home. It means cutting emissions and lowering your heating bills, too.

In fact, with tightening government regulations and soaring energy costs, there's no better time to make the change to triple glazing.

5. It reduces noise pollution

Excessive noise pollution can have a number of negative effects on your health and day-to-day activities – namely stress, sleep disturbances and reduced productivity.

Calder Windows' extra-thick triple-glazing system can help to make your home your sanctuary by dampening the thrum of traffic and minimising noise pollution.

6. It lessens the risk of damp

The additional glass pane and insulating space in our triple glazing can help reduce condensation in your home, lessening the likelihood of nasty water damage.

Minimise the risk of damp and mould and the potential health risks associated with them. Choose our glazing solutions and you can make your home an altogether more comfortable, healthier place to be.

7. It improves security

Enjoy extra peace of mind with our robust triple-glazed windows.

Not only can you expect a sturdy, high-quality installation, but the windows themselves are also designed to be a problem for any would-be intruders. The vast majority of our windows feature highly secure multi-point locking systems, while our doors are fitted with three-star euro cylinder locks from Yale.

8. It may increase the value of your property

Energy-efficient homes are becoming increasingly desirable. Thinking about selling your home in future? Our triple-glazing system doesn't just save pounds on your energy bills – it can also add value to your home in the long run.

9. It's very hard-wearing

Our triple-glazing system is weather-resistant and built to last. In fact, we're so confident in our product and the skill of our installers that you'll be covered by a 10-year insurance-backed guarantee as standard.

10. It looks great

With Calder Windows, you can choose from an extensive range of colours, styles and decorative glass panels. It's all about making sure your triple glazing is the perfect match for you and your home.

11. It's an investment that makes sense

Due to the added manufacturing complexity and additional materials needed, triple glazing typically costs a little more than double glazing. However, the extensive list of benefits – including increased energy efficiency and added curb appeal – make it an economically sound investment.

Get triple glazing for the same price as double glazing

Good triple glazing makes sense. But it comes at a price – most installers charge more for triple-glazed windows than their double-glazed counterparts.

But does it have to be this way? Do you have to pay more to get triple glazing installed?

Not with Calder Windows. Right now, we're offering a free triple glazing upgrade for all new customers in Yorkshire.

This means you can get all the cash-saving benefits of triple glazing for the same low price as double glazing .

If that sounds too good to be true, well… actually this time it is true. We really are offering triple glazing at no extra cost to our valued customers.

But hurry – this offer might not stick around forever. To claim your free triple glazing upgrade, simply get in touch with our team today.

5 creative uses for bi-fold doors

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 07 Apr 2025 16:20:48 GMT

There are many ways you can use bi-fold doors in your home. Discover 5 creative uses in our guide.

Bi-fold doors can be a stand-out feature of any home. They flood your living space with natural light and enable that enviable indoor-outdoor living many people dream of.

They're often seen spanning the width of a beautiful kitchen that leads seamlessly into a garden space. However, that's not their only use.

Yes – there are many creative ways to use bi-fold doors in your home. Below, we share some of our favourite non-traditional uses. Perhaps there are a few you haven't thought of?

Indoor-outdoor living

Sure, we live in the UK, where the chances of sunshine are often slim to none. But that only means we're even more determined to take advantage of good weather when it eventually strikes.

Perhaps that's why so many of us like the idea of indoor-outdoor living spaces. This is where homes are designed so the shift from indoors to outdoors is all but seamless.

For example, you might choose to install the same tiling in your kitchen and on the patio adjacent to it. Or pick matching indoor and outdoor furniture. It's all about making your home and garden feel like the same connected space.

Bi-fold doors help bring the spaces together, creating a beautiful and spacious environment to entertain guests and maximise your living area.

If you're tempted by this idea, you certainly won't be disappointed with bi-fold doors. Their large glass panes and foldable design mean your home will be flooded with natural light. They're perfect for bringing nature closer.

The creativity comes in how you decide to use them – the colours you choose and the details you decide on. As a trusted bi-folding door company , we can supply a wide range of colours and configurations to suit all tastes and any living space.

Open plan? It might as well be THE plan…

If you're a fan of the indoor-outdoor vibe, this should also be right up your street.

Open-plan living is all about creating flexible living spaces – and for that, you need flexible products. Thankfully, bi-fold doors are as versatile as they come.

For example, they can be used as room dividers to separate living and dining spaces. Or you could join up two sitting rooms while allowing the spaces to remain separate if needed. You could even connect a kitchen and a conservatory. The options are almost endless.

They're also great for home offices. Not only do they allow privacy during your working day, but they can also be opened when desired to let air and light flow through.

Whatever you're aiming for, bi-folds can make your vision come to life and transform your home into an open-plan paradise.

Maximising small spaces

If you look at a brochure for bi-folding doors, you'll come away with one distinct impression. These are domestic panoramas – wide, beguiling canvases of light that frame your house or garden like a landscape painting.

And sure, they're often at their best when used this way. But did you know you can also use them to create smaller, private spaces in your home?

Picture this. You have a master suite running across the entire width of your upstairs. You want to create a luxurious and spacious area that still feels private. However, you're not sure how to keep the light flowing.

You guessed it – bi-fold doors to the rescue!

Bi-folds can also be used on a bedroom balcony to allow a flow of natural light to sweep the environment. Or, if you'd really like to switch it up, they could divide your bedroom area and en-suite to keep the bathroom light and airy.

Upgrading pantries and cupboards

Pantries and cupboards are often neglected when it comes to home improvements. But if you want to make your home feel truly unique, it's worth giving them some thought.

Perhaps the cupboard under the stairs could benefit from a little more character. Or maybe you'd like to make your pantry more accessible.

Bi-fold doors let you swap those boring, utilitarian doors for something more stylish and modern. And all while keeping those spaces compact and accessible for storage and day-to-day use.

No one puts bi-folds in a corner… or do they?

Yes, this might sound a bit odd. But stick with us on this. We promise you won't be disappointed.

Bi-folds are, more often than not, installed on straight walls to separate two adjoining rooms or spaces. However, there's another way to use these doors that will elevate your space and make it a talking point among visitors.

Yes – if the layout of your home allows for it, bi-fold doors can, in fact, wrap around a corner.

This isn't an easy job. It involves removing one complete wall or window and the adjacent wall, then installing two sets of bifold doors at 90° angles. However, the results can be nothing short of stunning.

Imagine this. If you had one long, spanning bi-fold that opened out into the garden, you could extend that bi-fold around the side of your home.

The result? A panoramic view of your home from both the inside and the outside of the property. It would allow for a huge flow of natural light and the opportunity to really open up your home.

Final thoughts

We hope these bi-fold door suggestions have got you thinking. If so, why not contact our helpful team to discuss your ambitions? We'd be delighted to help bring your vision to life.

Our experts can run through everything from colour to size and those tiny finishing touches. With our help, purchasing your new bi-folds should feel easier than taking a trip to the supermarket!

How tilt-and-turn windows work

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 24 Mar 2025 06:47:19 GMT

Tilt-and-turn windows are great for safety, ventilation and durability. How do they work? Find out in our guide.

The modern-day window market is full of choices. Homeowners can choose between a wide variety of products, each with its own functionalities and its own pros and cons.

What to choose? It all depends on you and your requirements.

Even if you don't know the name, chances are you've used a tilt-and-turn window . They're a popular option, based on a mid-century German design, and come in uPVC, aluminium and wood.

Tilt-and-turn windows boast a range of benefits. They offer easy ventilation. They make cleaning a piece of cake. They're safe, stopping intruders from getting in and pets and children from getting out. If you source your windows from a reputable seller, they're durable, too.

As the name implies, tilt-and-turn windows have two functions. They can be tilted inwards to let outside air into the room. In this case, the window opens from the top and is hinged at the bottom.

Alternatively, they can be fully opened inwards in a horizontal fashion – with the hinged point at one side.

At Calder Windows, we stock tilt-and-turn windows made from high-quality materials and available in a range of colours and finishes. They're long-lasting, energy-efficient and attractive – and like all our windows, they're fitted with multi-point locking as standard.

That's what they do – but how do they work? It's all in the handle.

How do tilt-and-turn windows work?

When the handle is down, your tilt-and-turn window is closed. The handle is fitted with a lock.

Turn the handle to a horizontal position and the window will open inwards a full 90 degrees. This allows you to purge the room's air, combatting condensation and mould – or simply filling the room with natural light and warmth on a sunny day.

Turn the handle 180 degrees so it's pointing upwards and the window can be tilted inwards, creating a gap for ventilation. This lets in a draught without letting in any rain.

This mechanism may differ slightly between manufacturers, but the principles are the same. One handle position closes the window, one tilts it open a little and one opens it fully.

Are tilt-and-turn windows a good idea?

Tilt-and-turn windows aren't for everyone. But for many homeowners, they're a versatile, safe window that allows for easy ventilation and easy maintenance.

The clue to their versatility is in the name. Tilt-and-turn windows tilt – and turn! They offer two distinct functionalities where many windows only provide one. This gives you greater control over the airflow into your home.

The tilt function allows you to ventilate a room without creating a wide aperture for intruders to enter or pets and animals to escape. This makes them a popular choice for families with young children. Opening the window at a tilt also lowers the chances of a child getting their fingers jammed. Moreover, the swing hinge makes it highly difficult for anyone to force an entry.

On a fine day, you can open the window completely to let the fresh air come flooding in. But if it starts to spit or rain, you can tilt it to maintain the airflow and stop water from getting in.

They're attractive, coming in a range of colours and finishes and adding aesthetic appeal to your home. Decorative glass designs are available, for instance with the RegaLead range. While a tilt-and-turn window might look out of place in a traditional period property, they blend well with more modern and contemporary designs.

These days, windows are unprecedentedly energy-efficient. Tilt-and-turn windows from providers like us are tightly air-sealed, ensuring heat remains on the inside when shut. This can do wonders for your energy bills and is good for the planet.

Finally, tilt-and-turn windows are easy to clean and maintain. The swing hinge gives you easy access to both sides of the window. This means you can clean your tilt-and-turn windows little and often, avoiding ugly build-ups of grime.

Surely, you may be thinking, there's a disadvantage? Above all, it comes down to style. Tilt-and-turn windows look superb in many settings. But if your home is all beams and flagstones, you might want to look for an alternative.

Tilt-and-turn windows also tend to be on the expensive side because of their complex design. However, they're well worth the investment and will last a long time.

What are tilt-and-turn windows made of?

Tilt-and-turn windows are available in uPVC, wood and aluminium. Like the different types of windows, these different materials have their own unique features and benefits.

When choosing a material, you should consider your budget, your aesthetic preferences, your desired level of thermal efficiency and the lifespan you're looking for.

What's the difference between casement windows and tilt-and-turn windows?

Casement windows resemble tilt-and-turn windows. Both types of windows can be opened inwards. However, a casement window usually opens outwards but lacks the tilt-and-turn window's "tilt" function.

Casement windows are much older than tilt-and-turn windows. They've been installed in the UK since around the 18th century and were common until the introduction of the sash window.

Can tilt-and-turn windows open outward?

Tilt-and-turn windows can only be opened inwards due to their hinge mechanism. However, they can be tilted slightly inward or opened 90 degrees, giving them a versatile functionality that other windows, including casement windows, lack.

It would be physically possible to manufacture an outward-opening tilt-and-turn window, but manufacturers prioritise stopping rain ingress.

Who invented tilt-and-turn windows?

What do airbags, glue sticks and tilt-and-turn windows all have in common? They were all Deutsche Erfindungen – German inventions!

Tilt-and-turn windows were developed in Germany in the 1950s . In Germany, they're known as Dreh-Kipp-Fenster and, like the tilt-and-turn windows you see today, can be turned ( drehen ) or tilted ( kippen ).

Today, tilt-and-turn windows are popular all over Europe, especially in modern homes. Ask a German living outside Europe and they may express nostalgia for the windows of their youth.

Is it time to replace your soffits and fascias?

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 17 Mar 2025 09:00:01 GMT

Worn-out soffits and fascias can cause a range of issues. Find out when it's time to replace them.

Soffits and fascias are an often misunderstood part of a house's structure. To many, they're just a couple of odd-looking words you see on flyers and the sides of vans. In fact, they play a critical role in shielding your home from the worst of the Great British Weather.

Despite the defences they provide, repelling water and pests from under the eaves, we suspect most people couldn't tell you the difference – or when it's time to get them replaced.

But soffits and fascias aren't just about redirecting rainwater and preventing leaks. They also allow air to circulate between the roof and the eaves, preventing the unwanted build-up of heat, condensation and mould.

Even more than that, new soffits and fascias can seriously boost your property's kerb appeal. They're available in modern and traditional styles, firming up the lines of your building and blending in with your style.

Too often, however, people neglect to properly care for these unsung heroes of the rooflines. It's up there with cleaning the oven as a job that forever falls to the bottom of your to-do list.

Nevertheless, regular maintenance is essential to avoid damage to the soffit and fascia that can cause leaks, mould and pest infestations.

We hope you never need to get your soffits and fascias replaced. But if you do, give us a call . We use top-quality materials for a job that's easy on the eye and tough on the elements.

But first, what are the differences between the two?

What are the differences between soffits and fascias?

The fascia is the vertical band or board that runs along the lower edge of the roofline directly below the eaves.

Its primary function is to provide a smooth, level surface for gutters to attach to. It also protects any underlying roof components.

Soffits, by contrast, are the exposed surface covering the underside of the roof's overhang or the underside of the eaves. They're typically found between the exterior wall and the roofline.

They're often treated as a single unit. However, one distinction is important when you come to repair, replace or maintain your soffits and fascias. Soffits are vented, allowing air to circulate, whereas fascias aren't. Knowing the difference can help you identify the source of the problem.

Six signs you should replace your soffits and fascias

1. Visible damage

This is the number one sign that your soffits and fascias need replacing.

Cracks, splits, holes, discolourations, water marks, rotting wood: all are telltale signs that it's time to call the installer .

Gaps in the material are especially important to deal with because they stop the soffits and fascias from shielding your home from the rain. Putting off the problem will only make it worse. Don't leave your home exposed.

2. Damaged siding

Are the sidings below the soffit looking rotten? Is the paint peeling? This could be due to water damage caused by a damaged fascia. The corners of the fascia where the gutters meet are especially prone to leaks.

If the paint on the soffit itself is bubbling or cracking, you could be looking at a leaking roof. Either way, it's time to consider a fresh set of soffits and fascias.

3. Leaking or unsupported gutters

Leaking or unsupported gutters can damage both the soffit and the fascia. Leaks usually occur in the corners where two pieces of gutter meet and the sealant wears out.

Damage can also be caused if your gutters pull away from the fascia board and away from the house. This is typically caused by clogged downspouts overweighing the gutters. If you see this, check the soffit for damage.

4. Ventilation

Soffits are there to ventilate. If you have plywood soffits, poor ventilation can lead the soffits and even the roof deck to delaminate. This is a sure sign it's time for an upgrade.

6. Pest infestation

If you hear scratching in the attic, you may be suffering from a pest infestation. This could be caused by a hole in the soffit and fascia. Whatever measures you take to deal with the infestation, you should also replace the soffits and fascias, or at the very least plug the hole.

7. Water spots

If you see large brown spots or rusty nails on your soffits and fascia, you probably have a leaking roof. As well as fixing the leak, you should replace the affected areas. Otherwise, you're putting your home at risk of structural damage, mould growth and pest infestation.

If any of these signs apply to you, make sure to address them sooner rather than later. Leaving the problems unaddressed can lead them to snowball, leaving your home inadequately protected from the elements.

A modern set of soffits and fascias doesn't just offer protection, though. It can also improve the look of your home – and on the housing market, looks equal money.

But even if kerb appeal isn't your top consideration, good-quality soffits and fascias will help reduce the amount of time you spend cleaning and the amount of money you spend in the long run.

Replacing your soffits and fascias can be a great investment. But how can you avoid getting to the stage where they need replacing in the first place?

How to avoid replacing your soffits and fascias

As with so many things in life, maintenance is the answer.

This means regularly inspecting the soffits, fascia and adjoining walls for damage. It means cleaning out the gutters and ensuring they're properly aligned. It means trimming tree branches away from the roof line and fascia boards (they can make a real mess in a storm!) And it means gently power-washing your soffits and fascias at least once a year.

We hope you never need replacement soffits and fascias . But if you do, give us a call. At Calder Windows, we use top-quality materials for enhanced durability and aesthetics. Get in touch today for a quick, competitive quote.

Asking landlords to make home improvements: a renter's guide

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 10 Mar 2025 09:43:45 GMT

Are you a renter looking for home improvements to be made? Explore your options in our simple guide.

There are around 11 million private renters in the UK and 2.3 million landlords. When it comes to home improvements, those 11 million renters have few rights. However, there are some situations where improvements can be made.

Before we go any further, it's important to note a couple of things. First, nothing in this article constitutes legal advice. If you decide to negotiate with your landlord and want advice, you should contact a housing charity or renter's union.

Secondly, there's a distinction to be made between repairs and improvements. If something breaks, it needs repairing. An improvement, by contrast, is a job that will increase the value of the property. This is important because landlords are legally obliged to carry out repairs but not improvements.

Examples of improvements include disability adaptations, painting and decorating, new carpets, new furniture, a new kitchen, a new bathroom, heating and insulation.

When approaching this subject, it's also essential to remember that your landlord has the upper hand. They can either raise the rent or issue a section 21 eviction (also known as a "no-fault eviction"), though these are set to end at some point in 2025. You need to be confident that fighting for the improvement is worth it.

You should also be prepared to negotiate. Landlords typically rent properties to make money, not to provide you with a dream home. Often, a landlord will only make an improvement if it will increase the value of the home. This can, however, backfire on you in the form of a rent increase.

Can I make home improvements to my rented property?

Yes – but only with the landlord's permission. If you make improvements without permission, you could be forced to pay for the improvements to be undone. You could also lose your deposit or even face eviction.

Asking for disability adaptations

If you or a cohabitant is considered disabled under the Equality Act 2010, you can ask for disability adaptations.

These adaptations will need to be "reasonable adjustments". This means the landlord must agree that the adaptations are practical and affordable. Landlords can't charge you for any such improvements.

You can find more information and guidance about disability adaptations on the Scope website .

Painting and decorating

If your walls are looking shabby, you may want to ask for them to be painted and decorated. However, private landlords are under no obligation to do this for you – and you'll need permission to do it yourself.

It's different for council and housing association tenants, who are usually allowed to paint and decorate. Make sure to check beforehand.

New carpets or furniture

As with painting and decorating, there are no rules about replacement carpets and furniture for private landlords. You will need to ask.

If you need an appliance replaced, you may be covered by your tenancy agreement. If not, you can ask your landlord anyway.

New kitchens, bathrooms, heating or insulation

A private landlord might install a new kitchen, bathroom, heating or insulation to increase the value of the property. This could, however, lead to an increase in rent.

What if an improvement is needed for your health?

Private landlords need to make improvements if there's a risk to your health. If your landlord or letting agent ignores you or delays the improvement, you can ask the council to inspect the property.

Housing charity Shelter has a guide to the process .

If you live in a council or housing association property, you can ask the landlord for permission to carry out the improvement yourself.

How to ask a private landlord to carry out improvements

Private landlords want their properties to be profitable. This usually means any improvement will have to benefit them as well as you. It's what Roger Fisher and William Ury describe as "inventing options for mutual gain". In other words, you need to negotiate, not make a demand.

Typically, this mutual gain will be that the improvement will increase the property's value or make it easier to sell. However, this could come back to haunt you in the form of a rent increase or the sale of the property.

If you do decide to make the request, send a polite, friendly email or letter explaining why you're asking for the improvement.

You may stand a better chance of success if you've lived in the landlord's property for some time and have a good relationship.

As part of the negotiation, you could offer to pay towards the cost of the improvement. However, this can be a risky move if you have an assured shorthold tenancy. You may end up paying for an improvement you don't enjoy for long – and you may have to pay more rent.

If you manage to reach an agreement, make sure to get it in writing. This should include what you agreed, who is paying for what, a schedule of works and any agreement about changes to rent.

Support for renters

Renters may face consequences if they request home improvements. For instance, they can be forced to pay more rent or be evicted. (No-fault eviction, however, is likely to be abolished under Labour's Renters' Rights Bill .)

If you're worried about either of these things, you may find this list of housing charities and renters' unions helpful.

Conclusion

It can be difficult to get private landlords to make improvements to your rental home. Typically, they'll only be made if it's a "reasonable adjustment" for a disability or if it improves the value of the property. However, you may be successful if you've lived in the property for a long time and have a good relationship with the landlord. Good luck!

5 double glazing alternatives compared

simon@mydigitalhero.co.uk (Simon Edward) — Tue, 04 Mar 2025 15:02:17 GMT

Looking for an alternative to double-glazed windows? Join us as we run through 5 of your options.

Once upon a time, the UK was a colder place to live. Homes and offices were fitted with single glazing – a type of window that does the job in the same way that a summer jacket will keep you warm in winter.

Today, homeowners, landlords and business owners are spoilt for choice. Modern windows provide vastly improved insulation, meaning an all-round levelling up of comfort.

But it's not just comfort that double glazing and its alternatives provide. The thicker your windows, the less noise pollution you have to endure, whether it's the hum of traffic or the clatter of a neighbour's drum kit.

Thicker glass also makes your building more thermally efficient. By keeping the warmth in, you're far less likely to top up the temperature via thermostat. This can have a noticeable impact on your energy bill. It can also be a positive step towards a greener, more sustainable home.

Finally, double glazing helps you control condensation. This minimises the chance of your property being afflicted with mildew and mould.

At the time of writing, 93% of homes in the UK have double glazing. So, you may be surprised to learn that double glazing isn't the only horse in town.

In this article, we take a look at some of the alternatives to double glazing on the market and weigh up their pros and cons. We'll also tell you a bit about the free upgrade we offer from double to triple glazing.

Why would you need an alternative to double glazing?

There are two main reasons homeowners and business owners look for alternatives to double glazing.

The first is that owners of Grade II-listed buildings and properties in conservation areas need to seek permission to install double-glazed windows – and there's no guarantee these applications will be accepted.

A related but separate issue is that many owners wish to conserve the character of their properties. Double glazing could change the look of a property for the worse in the owner's eyes.

But there's a more general reason to look for an alternative. Double glazing is good for thermal insulation, soundproofing, moisture control and home security. But these days, it ranks second behind triple glazing.

Triple glazing gives you all the benefits of double glazing – only better. This incentivises an increasing number of landlords and property owners to make the change from double glazing.

1. Thermal curtains and blinds

Thermal curtains and blinds are designed to stop heat escaping in the colder months. While they lack the comprehensive thermal control of double and triple glazing, their special linings can help you manage the flow of heat into your home.

2. Shutters

In the olden days, glass was a premier product. This meant many people had half-and-half windows – the upper half was glass and the lower half a shutter.

There's a reason those days are behind us. Nevertheless, shutters can be a functional and affordable way of insulating your property when used in conjunction with good-quality glass. They can also help you keep out any unwanted external noise.

3. Secondary glazing

Shutters, curtains and blinds can do the job – up to a point. However, they have one main drawback. Unlike windows, they block out the light.

This isn't a problem at night. But during the day, you're restricting the amount of natural light coming into your building. This, in turn, means your energy bills will go up as you rely on electric light to make your building a hospitable place to be.

Secondary glazing sidesteps this problem. As the name suggests, it involves adding a second layer of glazing to the window. This is a popular choice for owners in heritage properties who want the advantages of double glazing without replacing the original windows.

4. Reglazing with vacuum-insulated glass

Reglazing with vacuum-insulated glass (VIG) is a great alternative to installing new double-glazed windows. Like double glazing, it offers a strong thermal performance, strong sound insulation and a good lifespan.

VIG is increasingly popular with owners of listed buildings. As with secondary glazing, it lets them improve their windows' thermal performance without replacing them altogether.

5. Triple glazing

For our money, triple glazing is the best alternative to double glazing on the market. It gives you all the benefits of double glazing – only better.

That means better thermal insulation, better home security, better noise reduction and a longer lifespan.

It's easy to see why. Triple glazing consists of a sealed unit with an extra glass pane, giving it a U-value of around 0.7 W/m²K and a sound reduction of around 35 decibels.

It's already popular in colder parts of the world. But more and more UK property owners are getting on the triple train. Aside from anything else, triple glazing is an investment that will make your energy bills more affordable in the long run – a great example of how technology can combine consumer satisfaction with environmental concerns.

How we can help

At Calder Windows, we count ourselves as loyal members of the triple-glazing fan club. We believe it does the job and then some – and that it's only a matter of time before double glazing becomes the new single glazing.

When you buy double glazing through us, we'll upgrade them to 40mm triple-glazed windows free of charge. These windows have an A++ energy rating and are up to 40% more thermally efficient than their double-glazed alternatives.

So, if you're looking for a warmer home, cheaper energy bills and a glazing solution with all the benefits of double glazing, only better, why not join our legions of happy customers and take advantage of our free upgrade?

To get involved, simply give our team a buzz on 01924 897 040 or get in touch online . We'd love to help you give your windows a face-lift that's good for your home, your bills and the planet.

What door lock do I have?

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 17 Feb 2025 11:13:37 GMT

Do you know which type of lock is on your front door? Get to know the different kinds of locks in our guide.

There are some things in life you don't need to know until you need to know. Like how to apply for a mortgage or change the belt on your tumble dryer.

Door locks also fall into this category. Most of us go through life without giving much thought to the locks on our doors. They're just kind of… there.

Inevitably, though, there comes a time when you must look your lock in the eye and ask, "What are you, exactly?"

Perhaps you need to replace, repair or upgrade your lock. Or maybe you're just curious.

In any case, we're here to help. In this guide, we tell you about the most common types of door locks and how to identify yours.

Euro cylinder locks

The euro cylinder is a standardised version of the pin and tumbler lock. This type of lock dates back at least 2,700 years. However, the modern version was invented by Yale in the 1840s.

"If it ain't broke, don't fix it", they say. The euro cylinder is a refined and updated version of Yale's 180-year-old design – and it's among the most common types of locks fitted on doors in the UK today.

How do you know if you have a euro cylinder lock? Start by asking yourself these questions:

Do I have a uPVC or composite door?
Is the lock fitted onto the door handle?
Does the lock have a protective surround?

If the answer to any of these questions is "yes", then you likely have a euro cylinder lock. It's especially likely if the lock is on your front or back door.

Euro cylinders have many advantages. They're easy to use, easy to replace and – if you use the correct security standard – hard to break into.

But not all euro cylinders are created equal. Poor-quality cylinders can be prone to burglary techniques like lock snapping. That's why we use super-secure, three-star rated Yale euro cylinder locks for all our uPVC and composite doors .

Three- and five-lever mortice deadlocks

These types of locks are most commonly found on wooden external doors. To determine whether you have one, look for these characteristics:

The lock is embedded into the door: this is why it's called a mortice lock – the lock is "morticed" into the door. In other words, part of the edge of the door has been cut away to make room for the lock.
It can be locked from both sides with a key: there'll be a keyhole on either side. This will be the only way to operate the lock.
It's a deadlock: this means the lock isn't fitted to a door handle, knob or latch. These locks have a locking mechanism, a keyhole and nothing more complicated than that.

You can also look at the lock plate on the edge of the door. This should be stamped with the number of levers in the lock (look for the words "3 lever" or "5 lever").

Five-lever locks are more secure than three-lever locks. However, both tend to be less secure than euro cylinder locks.

For this reason, mortice deadlocks are sometimes fitted alongside a deadlatch.

Deadlatches (and nightlatches)

Deadlatches are most commonly found on wooden and glass-panelled doors. They're very easy to identify.

They will not be the only lock on your door. If you have a deadlatch, you probably also have a mortice deadlock.
The locking mechanism looks different on the inside and outside of the door. On the outside, there's a keyhole. On the inside, there's a box-shaped locking mechanism with a handle.
The bolt is triangular and fitted to a spring mechanism. This causes the lock to engage automatically when the door is shut.

Now, you might be wondering, what's the difference between a deadlatch and a nightlatch?

Both types of doors usually have a metal "snib". This allows you to lock the latch from the inside or secure it in an unlocked position. This is useful if you want to pop outside without a key.

However, nightlatches can sometimes be forced open by slipping a credit card between the lock and the door frame. Not good.

Deadlatches add another snib to address this security flaw. This snib allows you to "freeze" the lock in position from the outside using a key. Once locked in place, it cannot be defeated using a credit card.

Double-locking deadlatches add even more security. These locks also have a keyhole on the inside, allowing you to lock the handle, too.

In any case, deadlatches and nightlatches are less secure than other types of locks. That's why they're never used as the only security measure on an external door.

Our approach to door security

At Calder Windows, we take your security very seriously. That's why we use Yale euro cylinder locks for all our doors.

Yale is the gold standard for home security. Its locks are trusted by homeowners and businesses around the world – and it's been this way for more than 180 years.

And it gets better. Our Yale locks are rated three stars for security – the highest rating available in the UK. They're so secure that they're recognised under the UK police force's Secured by Design accreditation scheme.

Our windows get similar treatment. They're fitted with highly secure multipoint reverse-action inline locking systems. Yes, it's a bit of a mouthful – but all those features are there to keep you and your family safe.

At the end of the day, that's what it's all about. We stick to the highest standards of security because we want customers like you to feel confident every time you lock your door.

Are you in the market for a highly secure, ultra-modern door or window ? Do you need replacement locks for your doors or an emergency repair? If you're in the Yorkshire area, don't hesitate to get in touch with Calder Windows for a free quote. Our friendly team will be happy to help.

5 home improvements that save you money in the long run

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 10 Feb 2025 08:48:06 GMT

Looking for home improvements that will improve your home's energy efficiency? Explore 5 of the best.

They say you've got to spend money to make money. This is nowhere more apparent than in the world of home improvements.

Many people, however, shy away from making those much-needed improvements. It's understandable – a big payment is a big decision that's not to be taken lightly.

That said, many of these improvements will save you money in the long run – from heating to insulation to our speciality, windows and doors.

This is primarily a case of making your home more energy-efficient. And when that's the aim, financial help is sometimes available.

5 home improvements that will save you money

1. Draught-proofing

Does your house have a draught? Sealing those unwanted cracks is one of the easiest and most cost-effective ways to improve your home's thermal efficiency.

You can either do it yourself or get a professional to do the job for you. Either way, it's estimated to save you between £25 and £35 a year.

2. Loft insulation

If your property has a loft, you may be losing heat unnecessarily. Getting your loft insulated can help slash your heating bills and carbon footprint. This is possible whether you have a "cold loft" or one with heating.

MoneySuperMarket estimates that loft insulation in a typical semi-detached house will cost, on average £930, and save £270 a year. Meanwhile, a detached house can cut its CO2 emissions by 1,000 kilogrammes a year.

3. Solar panels

Solar panels work by capturing energy from the sun and converting it into electricity. They provide free, renewable and clean electricity.

As well as cutting your electricity bills, solar panels let you store extra electricity for later use – or sell it to the grid.

The savings can be considerable. Energy Saving Trust estimates that "a typical home solar panel system could save around one tonne of carbon per year".

4. Getting a new boiler

If you've got an old boiler, you could be spending more than you need on your heating bills. That's because modern boilers are much more efficient, especially those of the condensing variety.

But the advantages of a new boiler don't stop at energy efficiency and lower bills. They can also be space-saving. This is all thanks to a combination of advances in technology and efficiency regulations such as Boiler Plus.

5. Upgrading your windows

Did you know that 18% of heat loss is because of old windows? This makes them one of the biggest culprits for energy inefficiency in homes across the UK.

By upgrading windows, you're improving their thermal performance and saving money in the long run by cutting your electricity bills.

This could be a case of upgrading your single-glazed windows to double or triple glazing . It could mean adding a secondary pane to an existing window. Or it could be as simple as fitting your windows with heavier curtains.

Whatever you choose, you need to make sure you get windows with a high energy rating. These ratings run from E (lowest) to A++ (highest). Calder Windows' triple-glazed windows meet the BFRC's A++ rating.

Can I get help with the cost of home improvements?

The most common barrier to home improvements is the initial outlay. You can, of course, pay for them on credit. But there are also schemes available to help you with the cost, on the condition that the result is a more energy-efficient home.

If you're looking into installing insulation, a new boiler or a renewable heating system, you could apply to the Boiler Upgrade Scheme , the Connected for Warmth insulation scheme, the Energy Company Obligation scheme, the Great British Insulation Scheme or the Home Upgrade Grant scheme.

As with all such schemes, you should check whether you're eligible before applying.

Do you live in an older home?

If you live in an older home, you may be resigned to the idea that it will always be draughty and energy-inefficient. In fact, old homes can have modern standards of performance with the right repairs and maintenance.

Improvements that will save you money in the long run include internal and external shutters for enhanced thermal control, roof insulation, and hot water storage tank and pipe insulation.

You can also replace the windows to ensure the heat stays in or out, depending on the weather. This will have the added advantage of improving the durability and security of your windows.

Should I get spray foam insulation?

Some companies and customers swear by spray foam insulation. However, the government advises against it, pointing to "risks that could cost you money" and potentially undo its money-saving effects.

These include condensation, dampness, property devaluation and the risk of covering problems such as leaks or damaged wood that should be fixed. The government advises you to seek independent advice from a building surveyor before committing to spray foam insulation.

What if you're a renter?

When it comes to home improvements, renters have different rights than homeowners. If you're a renter, you must seek your landlord's permission before making any improvements.

Your landlord should make improvements if your Energy Performance Certificate (EPC) classifies your home as band F or G. However, homes in this band can be registered as exempt from minimum standards of energy efficiency.

Complaining to your landlord or letting agent about a lack of home improvements can be risky. In some cases, it can lead to eviction. For this reason, it can be advisable to seek independent advice from a housing charity before complaining.

What if you live in social housing?

If you live in social housing, the landlord is legally obliged to make sure your heating and insulation are up to standard and your home is "reasonably warm". If this isn't the case, you have the right to request repairs and improvements.

Are you looking to upgrade your windows? When you buy double-glazing from Calder Windows, we'll upgrade you to triple glazing at no extra cost. Get in touch today to take advantage of this cash-saving offer.

Can a conservatory be built over a drain?

simon@mydigitalhero.co.uk (Simon Edward) — Fri, 07 Feb 2025 17:01:58 GMT

What happens if you want to build a conservatory over a public drain? Get the answers in our guide.

Getting a conservatory installed is a great way of expanding the potential of your home.

Of course, a well-built, well-maintained conservatory is a pleasant place to be in pretty much any environment. But it can also blend with your home's aesthetic, add to its market value and maximise its floor space.

So far, so good. But what if you want to build a conservatory over a drain?

This introduces two complications. First, building a conservatory over a drain, or even in close proximity, can damage the pipes running nearby. Secondly, water authorities need access to drains. Your conservatory could make that impossible.

For this reason, there are some steps you should take before getting the builders in. We hope this article helps you figure out the best way to proceed.

Rules and regulations

Your home, your rules? Not so fast. Public drains belong to the water and sewage companies, so building a conservatory on top of them creates a conflict of interest.

The key consideration is whether your proposed extension will be within three metres of a public drain. If it is, you need to get in touch with your local sewerage company. You can find your local supplier on the Water UK website .

They will assess the risk that your conservatory poses to the pipes. If they consider it major, you should look for another location. If, however, they think the risk is negligible, you get the green light to go ahead and start installing your conservatory.

It's also important to note that you can't build over a manhole. These always need to be accessible for maintenance, regardless of whether they're sealed or not.

What happens when you get the green light?

So, you've sought and gained approval for construction from the water company. Before you go any further, you need to plan carefully to ensure the drain in question can be accessed for maintenance and repair.

In this situation, there are a number of things to take into consideration.

Technical considerations

First, there's the foundation of the conservatory. If the drains are shallow or the conservatory will affect the lower end of the drain pipe, you may need to dig deeper foundations.

Your foundations should also be built in such a way that they don't shift over time. This can put unwanted pressure on the drainage system.

This also applies to the building materials you use. You will need to use high-quality materials that won't damage the drain and will distribute the weight efficiently.

The roof, too, needs consideration. You may want to add cavity trays and flashings where the roof meets the wall of your house. Otherwise, you could be looking at leakages.

Finally, you will need to ensure that access is available for maintenance. This could mean installing access points.

It's a lot to think about – and your priority should be getting expert advice from your conservatory installer. They will be able to recommend the right materials and install the conservatory in such a way that it doesn't block or damage the drainage system.

What to look for in an installer

If you get permission to build a conservatory over a drain, your best bet is to get advice from an experienced installer. They will have the skills and expertise you need to ensure a safe, stable, fit-for-purpose installation.

As well as looking for positive online reviews and listening to word of mouth, you should also check that the company is properly licensed, insured and accredited. These objective standards help give you peace of mind that you're working with the right firm.

The right installer can be the difference between the conservatory of your dreams and a logistical nightmare. Make sure to shop around before you sign on the dotted line.

An exception to the rule(s and regulations)

Building a conservatory over a public drain is a problem precisely because the drain is public and the water company may need access.

If, however, the sewer is private and not connected to the public system, you don't need to seek approval.

Even if this applies, you should think carefully before beginning construction as you don't want to damage the pipes or block access.

What happens if you don't get approval?

If you don't get approval from your water company, you shouldn't build your conservatory. This is because the water company need access to the drains.

If you decide to go ahead regardless, you may find yourself in conflict with the water company. They will reserve the right to remove the conservatory to gain access. Fighting this will take a lot of time, energy and money.

On balance, it's rarely worth building a conservatory over a drain without proper permission and proper planning. With any luck, you should be able to get your conservatory installed elsewhere on your property.

Can I build my conservatory over a manhole?

You can't build a conservatory over a manhole as it needs to be accessible to the water company. However, if you get approval, you may be able to relocate the manhole. There are also systems available that install removable access panels.

Do I need planning permission for a conservatory?

Most of the time, you don't need planning permission to build a conservatory on your property. There are, however, exceptions. These relate to the size and position of the proposed extension, as well as rules regarding designated areas and listed buildings.

Even if nothing stands out to you as unusual about your planned conservatory, it's worth checking to avoid disappointment. If you break the rules, you could be asked to retrospectively apply for planning permission, remove the extension or even pay a fine.

Perhaps, however, you're wondering what all the fuss is about. Maybe you've even heard a few myths and misconceptions about triple glazing that are making you think twice.

We're here to put those myths to bed. Here are six tall tales about triple glazing – and the truth behind them.

1. Triple glazing is more prone to internal condensation

WRONG.

It's true that you're more likely to see condensation on the outer panes of triple-glazed windows. However, this is a sign that they're doing a good job.

See, water condenses on windows when there's a temperature difference between the panes and the air around them. Triple-glazed windows trap heat and make the air in your home warmer. This causes moisture in the warm air to form droplets on the cool panes.

Triple glazing works better than double glazing. It traps more heat, so it causes more condensation. It doesn't mean your home is damp or the windows are faulty. You can simply wipe off the water droplets and pat yourself on the back for choosing good glazing.

But let's be clear – more external condensation doesn't mean more internal condensation.

Double- or triple-glazed windows only fog up on the inside when they're faulty. This is more likely to happen with old or poor-quality windows. But if you choose good, sturdy, modern triple glazing, you can expect decades of bill-busting performance with minimal maintenance.

2. Triple glazing makes your home feel dark and gloomy

WRONG.

This myth has its roots in the fact that triple glazing lets in slightly less light than double glazing.

It makes sense – sunlight has to pass through one more pane of glass, so you'll inevitably lose a little light in the process.

But this is glass we're talking about. Glass is about as transparent as you can get.

Chances are, you'll barely notice the difference. At worst, you'll have to turn on the lights a little earlier – but the heat efficiency gains will almost certainly outweigh any increase in electricity bills.

3. Triple glazing won't help with noise

WRONG.

Triple glazing will help deaden traffic noise and other sonic disturbances. But it's true that it might not help as much as you think.

It all depends on the type of noise and how loud it is. See, occasionally, the extra pane of glass in triple glazing can vibrate when exposed to certain sounds. This can lessen some of the sound-insulating benefits you get from that extra pane of glass.

For best results, you should choose special acoustic glass that's designed to minimise vibration. Or, as a quick and affordable solution, you can improve its sound-insulating properties by installing a simple acoustic film.

Your choice of installer can also make a difference. Choose a trusted firm and you're more likely to get a tight, professional seal. This means less noise and fewer problems down the line.

On which note…

4. Triple glazing requires additional maintenance

WRONG.

With good-quality glazing and a professional installation, you can expect triple-glazed windows to last for up to 35 years. And just like double glazing, it requires only minimal maintenance. A quick wipe every now and again will keep the windows looking as good as new.

But, again, it all comes down to quality. Sure, a cheapo brand might save you a bit of cash in the short term. However, if you have to pay for new seals every few years, that day-one bargain will seem like a decades-long headache.

5. Triple glazing looks weird

WRONG.

This is an easy one.

Triple glazing doesn't look weird – it looks like double glazing. Even our extra-thick 40mm triple-glazing units are almost indistinguishable from their double-glazed counterparts.

Besides, new windows are almost always a visual upgrade – especially if your existing units are on the older side.

6. Triple-glazed windows aren't worth the extra money

WRONG.

There's no getting around the fact that triple glazing costs more than double glazing.

However, the gains in thermal efficiency – and reduction in energy bills – mean that triple glazing will almost certainly pay for itself with time.

How much you'll save depends on the state of your existing windows and the quality of the triple glazing you choose.

The difference between single glazing and triple glazing is night and day. You'll feel like you've moved from an igloo to an air-conditioned palace – and slashed your heating bill in the process.

But going from double glazing to triple glazing is still a big jump. Our extra-thick, super-insulated triple glazing, for instance, is a whopping 40% more energy-efficient than its double-glazed equivalent.

And get this – with Calder Windows, you can take advantage of these energy savings without paying an extra penny.

Are windows a capital improvement? Your expenses explained

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 20 Jan 2025 11:00:37 GMT

Do new windows count as a capital improvement in your tax return? Get the answers in our explainer.

If you're a landlord, you naturally want the best return on any repairs or improvements you make to your property. To make this calculation accurately, you need to know how the investments you make will be taxed.

Goodness knows it isn't always easy. Accountant training takes years rather than months for a reason. Property tax is intricate, extensive and often not intuitive.

This is apparent in the example of windows. Let's say you want to replace the windows in your property. Will they be tax deductible? Alas, there's no straightforward yes-or-no answer.

Instead, the answer hinges on the extent and nature of the replacement. These will determine whether the investment is regarded by HMRC as capital or revenue expenditure.

So, before we go any further, what's the difference between these two types of expenditure?

Capital vs revenue expenditure

Revenue expenditure is all about the day-to-day. It refers to the costs you, as a landlord, will pay in the everyday running and maintenance of your rental property. These costs can be deducted from your taxable income.

It tends to cover recurring costs: things like letting agent fees, advertising costs, maintenance – and repairs.

Capital expenditure, by contrast, refers to investments that improve or extend the life of the property. These are not fully deductible against your rental income.

Capital expenditure covers the following:

Significant structural changes, improvements and extensions
New fixtures, fittings or features that aren't "routine"
Conveyancing fees, surveyor fees and other legal fees incurred when acquiring the property
External improvements that enhance the property's appearance
Significant landscaping work

So, what about windows? The short answer is that it depends on whether the new windows are considered by HMRC to be a repair or an improvement.

A repair is classified as revenue expenditure and is therefore tax-deductible. An improvement, however, counts as a deductible capital expense.

So, before you commit to replacing your windows, you need to be clear about whether it will be classed as a repair or an improvement. What, exactly, are the differences?

What's the difference between a repair and an improvement?

We're not tax advisers. If you have one, ask them for advice about the work you have in mind. If, however, you're self-employed, your go-to source is HMRC's Business Income Manual or BIM. In particular, you need to refer to BIM46900: "Specific deductions: repairs and renewals".

Here are some of the factors that BIM46900 encourages you to consider. Please bear in mind that this summary is not exhaustive. It's simply here to point you in the right direction.

First, a distinction is drawn between "repairing a worn or dilapidated asset" and "replacing the whole or the 'entirety' of an asset". The first is a repair and, therefore, an allowable expense. The second counts as capital expenditure.

Next , you need to clarify whether you're restoring an asset to "what it originally had been" (a repair) or altering or improving the asset (an improvement).

In the case of windows, this distinction could apply if you were restoring a window to its original condition versus upgrading the windows to be more thermally efficient.

"Care needs to be taken," the guide goes on, "where a programme of works has been carried out as some works may simply be repairs, while others are alterations or improvements." In other words, you must make the distinction on a job-by-job basis.

The use of modern materials for replacement windows may count as an improvement – but only "if, as a result of the work, more can be done with the asset, or the asset can be used to do something that it could not do before".

If, however, the asset does the same job as before, it counts as a repair and not an improvement.

The same goes for the use of new technology . BIM gives the example of double glazing. Once upon a time, this counted as an improvement. Today, it's standard. This means it's now counted as a repair.

This is something to take into account if upgrading windows in a way that uses new technology. Is the technology sufficiently new that it counts as an improvement, or is it industry-standard and classified as a repair?

Next , there's the question of repairing, altering or improving second-hand windows. The cost of the repair counts as a capital expense if and only if "it is effectively part of the cost of acquiring the asset".

Finally , there's the question of what happens when a property is leased. If the tenant "agrees to restore the property to a good state of repair, then the repairs are capital expenditure".

As we've said, this isn't an exhaustive account of BIM's distinctions between tax-deductible repairs and improvements that count as capital expenditure. However, we hope it points you in the right direction and helps you decide whether to invest in new windows.

So… are windows a capital improvement?

By this point, it will be clear that the simplest answer isn't simple at all: it depends.

It primarily depends on whether your replacement windows are considered by HMRC to be a repair or an improvement. This, in turn, depends on whether:

You're repairing dilapidated windows or replacing them in their entirety.
You're restoring windows to their former condition or significantly improving them.
The use of modern materials means "more can be done" with the windows.
The technology used is new enough to count as an improvement.
The replacement forms part of the cost of acquiring the asset.
The property has been leased and the tenant has agreed to repair the windows.

When in doubt, ask a tax adviser. They'll help you to make the necessary distinctions and clarify whether your replacement windows count as a tax-deductible repair or a non-tax-deductible capital improvement.

How windows are installed, step by step

simon@mydigitalhero.co.uk (Simon Edward) — Fri, 17 Jan 2025 07:11:44 GMT

When you get professionals to install your windows, what can you expect? Find out in our 5-minute guide.

Getting windows installed or replaced is a big deal. It can make a huge difference to your home – from aesthetics to insulation, from your energy bills to its market value.

But if you're considering calling in the installers, you may have a reservation. What, exactly, does it involve? Translation: how long will it take and will my house be turned upside down?

As worries go, it's far from unreasonable. A bit of disruption is the price you pay for home improvements. But no one wants to live in a building site for longer than is absolutely necessary.

The good news is that most jobs can be completed in a day or two – from removing the old window all the way to the final checks.

Still hankering for more details? We've got you covered. Read on to find out the step-by-step installation process along with factors that affect how long it could take.

How are windows installed?

Not all window installations follow the exact same procedure. However, a good job will typically involve the following steps.

1. Clearing the area

First, the area has to be cleared. The installers will need free access to the window frame. Without this, they won't be able to complete the job to a professional standard.

This is the part that some customers dread. Blinds and curtains are taken down. Furniture and ornaments on both sides of the window are removed. But fear not: the job will be over soon and everything put back in place.

2. Removing the old window

The windows are unscrewed at the hinges. Beading and putty are removed and the panes are taken out. Then the frame itself is taken out with a pry bar and hammer.

Next, the window opening needs to be cleaned. This involves removing any debris or bits of old caulking. New caulk is applied – a crucial step to avoid leaks and drafts.

3. Installing the new window

The new window is installed from the outside and adjusted so it's level. It's then secured in place with screws. Insulation is added to the frame and the window is trimmed and sealed.

4. Final checks

Next, the installer checks the window is plumb, level and square, and that it operates properly. Shims can be used to make adjustments where necessary.

5. Tidying up

Now the window has been installed, it's time to put things back in place. It won't be long before your house is a home once again. Phew!

How long will it take?

This is the million-dollar question: how long will the professionals be in your house?

Well, a standard window can be installed in an hour or less. A replacement window could take around an hour.

More complex, customised or non-standardised windows will naturally take longer. A bay window, for instance, could take two or three hours.

Bad weather can prolong the job, especially exterior work. You could also be looking at a longer job if the windows are in a hard-to-reach spot.

You should also take into account whether the installers will add insulation or weatherproofing. This will, of course, add a bit of time to the process.

In short, a window can be installed or replaced in less than a day. If the job involves multiple windows or complex windows (or is interrupted by bad weather), it could take longer.

That's how long the house will be a building site. But you should also take into account delivery times. You may need to wait for the windows to be delivered or even manufactured. Find this out from your installer ahead of time to avoid disappointment or frustration.

Can windows be completely installed from the inside?

Most of the time, windows are installed from the outside for ease of access. This is one way that installers can minimise the mess inside your home.

In some buildings, however, windows are installed entirely from the inside. These include historic properties, blocks of flats, high-rises and buildings where the windows simply can't be reached from the outside.

Can I do it myself?

The answer is, of course, yes. Some jobs should only ever be done by professionals – brain surgery, say. But home improvements can be a rewarding DIY activity. It all depends on your skill level, your willingness to learn, your patience, your resources and your time.

If you've got a gift for DIY, go ahead. The internet is bursting with how-to guides and the world is full of experienced installers who can point you in the right direction.

If, however, it all sounds too much like hard work, get a professional in. They'll apply all their skills, experience and eye for detail to the task, drastically reducing the chances of a botched job. It can be the difference between so-so and yes, yes, yes.

The main causes of regret following DIY installations relate to evenness and caulking. If the window is uneven, it can be difficult to open and close. And if the caulking is done less than perfectly, leaks and drafts become a strong possibility.

These aren't just a nuisance. They're also bad for your energy bills. Don't end up paying more than you need because of a substandard job!

Why your door makes noise when you open it (and how to hush it)

simon@mydigitalhero.co.uk (Simon Edward) — Thu, 16 Jan 2025 10:14:42 GMT

Squeaky door giving you grief? Figure out why it's squeaking and how to fix it in our handy guide.

Few things in life are more annoying than a squeaky or creaky door. After all, doors are there to be used. If a door makes a noise when you open it, you're probably going to be hearing it a lot .

It's not, however, the easiest problem to diagnose. There are several reasons why a door could make an irritating noise. Some can be fixed with a little lubricant. Others call for replacement hinges or even a replacement door.

We hope for your sake it's a quick job. But if not, we can help you get a replacement door that fits your property, be it residential or commercial.

First, though, what are the causes of a noisy door – and how can you make it go away? We start with the commonest cause of all: dry hinges.

Dry hinges

When hinges get dirty or dry, they can create friction. And in the context of a door frame, friction equals noise. Dirt, dust or a lack of lubrication between the hinge and the hinge pin leads to the unpleasant sound of metal scraping against metal.

The solution to this problem is lubrication – but lubrication can take many forms.

A short-term fix is to use hairspray. Simply spray it on the hinge then open and close the door a few times to spread it.

You can also use bar soap. This is a method that's been used since at least 1400 BC. Archaeologists have even found traces of soap on chariot axles.

Today, it works just as well. Just make sure you use bar soap with a high fat content.

Other possible lubricants include a few drops of olive oil, petroleum jelly, paraffin candles, silicone spray and lithium grease.

For a more thorough job, remove the hinge pin and coat that too.

If lubrication doesn't fix the problem, there could be another reason for the squeak, creak or other irritating noise. This could be an issue with the screws, the hinges or the door itself.

Is there a screw loose?

The screws joining the hinges to the door or the door frame can rattle when they come loose.

This is an easy problem to diagnose and fix. Check all the screws and tighten any that are loose. Your problem should quickly go away.

Are the hinges bent?

When hinges get bent, they can rub against each other. This rubbing of metal on metal can lead to an unpleasant squeaking or creaking sound.

To find out whether this is the noisy culprit, you'll need to remove the hinges to see if they're bent out of shape. If they are, you'll need to replace them.

The world of door hinges is surprisingly complex. You should be able to find a replacement hinge either by searching online or taking your bent hinge to a hardware shop. But if you're struggling, check out our door hinge guide .

Has the wood warped?

Old houses are always changing shape. This is primarily because changes in humidity can cause wood to warp. In the case of doors, this can create friction between the door and the frame – friction that makes a noise.

To fix warped wood, your first port of call is to sand it down. If this doesn't work, you may need to get the door replaced. Modern door materials won't warp – so it's well worth the investment.

If you can't afford a replacement door, consider getting a humidifier or dehumidifier to control the humidity in your home.

Is the weatherstripping worn?

When your door's weatherstripping gets worn away, it doesn't just make a noise – it also leads to drafts. These, in turn, can lead you to spend too much money on your heating bills.

Replacing old or worn weatherstripping is a relatively easy job. Look up a DIY tutorial and your problem could be gone in a matter of hours.

Is the door misaligned?

Sometimes, the noise from your door is because of structural misalignment. This could be because of loose screws – in which case, you know what to do. But it could also be that the door is hanging too low in its frame and scraping the floor.

In this situation, you can either adjust the hinges or plane the bottom of the door. This is a slightly more complex affair than tightening the screws. If you're a dab hand at DIY, you can certainly do it yourself.

If, however, you think it's more trouble than it's worth, it could be time to get a replacement door. This is where we can help.

Get a replacement door

A replacement door is a big deal. After all, this is an object you'll probably open and close thousands of times.

At Calder Windows, we provide a wide range of high-quality doors in various styles and materials. We also offer plenty of choice when it comes to door glass and door furniture – handles, knobs, numbers and letterboxes.

How do you stop your doors squeaking in the first place?

So far, we've looked at fixing the problem. But how can you prevent it altogether?

Your best bet is to lubricate the door hinges two or three times a year. This removal of dust and debris will drastically reduce the chances of a squeaky door.

You can also invest in door hinges made out of rust-resistant materials such as brass or stainless steel.

Finally, you can invest in a composite door that won't warp in the frame.

There's no escaping the fact that noisy doors are a nuisance. That doesn't mean, however, that you're stuck with them for good. We hope this article helps you fix the problem or stop it happening in the first place.

Will conservatories be banned in the UK?

simon@mydigitalhero.co.uk (Simon Edward) — Fri, 10 Jan 2025 11:07:24 GMT

In 2022, reports claimed new conservatories were to be banned. Sort the facts from the fiction with our help.

A few years ago, the media was briefly ablaze with rumours that new conservatories were to be banned in the UK. Could it be true?

Well, no. But like so many media distortions, there was a grain of truth behind it. Conservatories weren't and aren't going to be banned. However, new rules were introduced in June 2022 specifically relating to new-build properties.

These rules state that new conservatories can't be built on new-build properties unless it can be proved that they don't create "unwanted solar gain".

The measures have been introduced as part of the government's various initiatives to tackle the climate crisis. Related rules and regulations now apply to thermal control in new homes.

I have a conservatory – does this affect me?

No. These new rules do not apply to existing conservatories. They only apply to new conservatories on homes built after June 2022.

I'm planning to build a conservatory – does this affect me?

If your home was built before 2022, you can proceed with your conservatory project as planned. If, however, your home was built after 2022, you can only build a conservatory if it meets regulations.

If your new conservatory is to be larger than 30 square meters, you may need to fit it with a ventilation system to stop it from overheating. This could consist of adequate windows and doors, a mechanical ventilation system or a combination of the two.

Meanwhile, the roof on a new-build conservatory must have a U-value of no more than 0.15 W/m²K. Refurbished roofs must have a U-value of no more than 0.16 W/m²K.

Moreover, your conservatory must be separated from the rest of the house by exterior walls or doors.

What are the 2024 conservatory regulations?

As well as the rules around conservatories on new-builds introduced in June 2022, there are also conservatory regulations brought out in 2024.

These are updates rather than a complete overhaul. They build on existing regulations about the energy efficiency and safety of new conservatories.

Under the new regulations, conservatories have to meet minimum standards of insulation and specific percentages of recycled or eco-friendly materials.

The regulations also require contractors to learn more about sustainable building practices and make the building permissions process easier.

The main aim of these new regulations is to reduce conservatories' carbon footprints. This is part of a wider effort to make domestic and commercial buildings more sustainable.

Could the 2024 conservatory regulations affect my home's resale value?

Conservatories are more than just a pretty feature. They can also add resale value to your home. But will these new regulations affect that?

In fact, the opposite is true. Non-compliance with the regulations will make your home less, rather than more, resalable. This is partly because buyers want homes that are easier and cheaper to heat.

That's why it's really important to choose an experienced conservatory installer that complies with modern building regulations. If, on the other hand, your conservatory is already in place, you may want to consider fitting a thermal conservatory roof .

How have the rules about conservatories changed over the years?

Conservatories have been popular in Britain since the 19th century. Advances in glass manufacturing meant wealthy families could have glass sunrooms in their gardens.

As time went by, rules were introduced about structural integrity. These were primarily in place to stop conservatories from falling over or getting damaged in bad weather.

Since then, rules have been introduced to make conservatories more energy-efficient. They form part of a wider package of building regulations designed to address the climate crisis.

What are U-values?

A U-value is a measurement of how well a building component transmits heat from the inside to the outside of a building. It applies to walls, windows, roofs and doors.

U-values are measured in watts per square meter per Kelvin, written as W/m²K.

The lower the U-value, the better for your home's energy efficiency. A low U-value means good insulation and limited heat loss.

As of June 2022, the U-values of conservatory roofs are prescribed by the new regulations. A new-build roof can have a U-value of no more than 0.15 W/m²K and a refurbished roof no more than 0.16 W/m²K.

How can I cool down my conservatory?

It's an all too common complaint. Homeowners invest in conservatories that turn out to be sweltering in summer and Arctic in winter.

Luckily, you don't have to be lumbered with such a thermally inefficient albatross forever. There are steps you can take to increase thermal control in your conservatory.

The first is to install bi-fold doors. These open up fully, helping you ventilate your glass house in summer.

If you do go down the bi-fold route, consider a set with aluminium frames. The slim sight lines maximise how much natural light can enter your conservatory.

But perhaps the best way to cool down your conservatory is one that also improves its energy efficiency: upgrading the roof.

How can a new roof make my conservatory more energy-efficient?

Over the last 40 years, glazing, in general, has become substantially more energy-efficient. Yet many homeowners still have conservatory roofs made out of low-quality glass or polycarbonate. These are the top culprits when it comes to wild variations in temperature across the year.

Perhaps the best way to tackle this problem is to invest in a SupaLite roof .

This roof system consists of a lightweight aluminium frame, rigid insulation, a waterproof membrane and sturdy tiles. It's compliant with UK building regulations and helps maintain a comfortable temperature all year round.

On top of this, it reduces the likelihood of leaks, creates extra space at the top of the conservatory and can even add value to your home.

A conservatory is an extension of your home's aesthetic. To this end, SupaLite roofs come in a variety of finishes that can express your personality.

In our opinion, it's unrivalled in its versatility, energy efficiency and aesthetic appeal.

What door hinge do I need?

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 30 Dec 2024 17:14:08 GMT

Shopping for door hinges and don't know where to start? Check out our handy guide to your options.

Door hinge starting to squeak or looking a bit on the rusty side? It's high time to get a replacement.

"Simple", you say to yourself. You'll just pop to the nearest DIY store or log into Amazon and get a duplicate. Soon, your door will be gliding open and shut with the grace of a figure skater.

Then you get to the store and are met with an array of shapes and sizes. There are butt hinges, barrel hinges, parliament hinges and blunderbuss hinges (OK, we made that last one up). There are different thicknesses to consider. There are different hinges for different door materials.

What to do? Well, before you decide that you can probably do without doors altogether, take a look at our guide to the wonderful world of hinges.

How do you choose a door hinge?

Before you take a hinge to the counter, you need to take three things into account.

First, what kind of door is it for? Some types of hinges work with both internal and external doors. Others, however, are for internal or external doors only.

Secondly, you need to know what your door is made of. Wood or composite doors will usually take screw-type hinges. Metal doors, by contrast, will need weld-on hinges.

Finally, you need to think about the door's weight. Heavy doors call for heavy-duty hinges. Brass just isn't going to cut it.

Types of door hinges

Picture a door hinge, and you're probably thinking of a butt hinge. This two-sided hinge is ideal for lightweight doors, both internal and external. They're not suitable for fire doors or heavy doors.

A more heavy-duty variety of the butt hinge is the ball bearing hinge. These tend to last longer and aren't so prone to squeaking. However, they also tend to require more maintenance.

2. Spring hinges (self-closing hinges)

Spring hinges, also known as self-closing hinges, close the door behind you by pulling the door into the frame with a spring. These are often used on external doors and internal glass doors.

3. Flush hinges

A flush hinge is a small, lightweight hinge. One side – or "leaf" – fits into the other, resulting in a flush finish. This makes them ideal for cupboards, cabinets and lightweight doors.

They're extremely easy to install. Unlike butt hinges, there's no need to cut a recess into the door. Instead, they're simply screwed into place.

4. Parliament hinges

Parliament hinges come under different names, including projection hinges and wide-throw hinges. This last term tells you all you need to know. This type of hinge throws the door wide, projecting it away from the frame until it swings flat against the wall.

As well as working wonders for outward-opening French doors, parliament hinges can make doorframes accessible for people in wheelchairs.

5. Stop hinges

The purpose of a stop hinge is to prevent the door from opening too wide and hitting the wall. There are several different versions of stop hinges, but they all achieve the same thing.

Size matters

Now you know what style of door hinge your door will take, you need to figure out the size you need.

The size of your door hinges will depend on how big and heavy your door is. Find out the size you need by unscrewing the middle hinge and measuring the height and width with a measuring tape. If the hinge isn't square, you need to measure the corner radius instead.

The size and weight of your door will also determine how many hinges you need. Most doors need three. However, some smaller, lighter doors can be fitted with just two. Bigger, heavier doors will need four.

If the door is fire-rated, you need to fit three four-inch fire-certified hinges.

Most of the time, the top hinge will be screwed five inches from the top of the door and 10 inches from the bottom, with a third hinge halfway between where appropriate.

How can I stop my door hinges from squeaking?

If your home is plagued by squeaking door hinges, you've got options. Here are five of them.

Lubricate the hinges with silicone spray, petroleum jelly or a bar of soap.
Remove the hinge and clean off any dirt, rust or grime with a solution like WD-40 until they're un-squeaky clean.
Tighten the screws until the squeak stops.
Apply olive oil to the hinges using a pipette or spray can.
Spray extra-strong hairspray directly onto the hinges.

If none of these methods work, it's time to buy a new hinge.

Unlike door installation, replacing a screw-on hinge can be done DIY with relative ease. You just need a method to follow, doorstops to keep the door steady as you replace the hinges, a tape measure and a screwdriver or drill.

If the door itself needs replacing, you will almost certainly need a professional door fitting service (leaving aside any DIY kings and queens!)

How long have hinges been around?

Hinges have been unearthed from as long ago as Ancient Egypt. Different specimens are made from stone, marble, wood and bronze.

The Romans hung their door on pivot hinges. Known as "cardo", these gave their name to Cardea, the ancient Roman goddess of the hinge.

Of course, not all doors have hinges – think of roller shutters or sliding doors. Nevertheless, a world without hinges is hard to imagine. They're one of those little things that make all the difference.

If you need to replace more than just a hinge, we can help. At Calder Windows, we've been installing and replacing windows and doors in West Yorkshire for more than three decades.

How to clean windows you can't reach

simon@mydigitalhero.co.uk (Simon Edward) — Mon, 30 Dec 2024 11:29:49 GMT

Do you have a window in a hard-to-reach place? Find out how to clean it in our handy explainer article.

Do you have a window that's hard to reach? Chances are it's not your favourite domestic job. It might even be one of the chores you put on the to-do list marked mañana .

Nevertheless, clean windows are vital for homeowners and renters alike. So, how do you get the job done without risking your neck?

Well, you've got options. Let's take a look at them, starting with the most familiar.

1. Use a ladder

Not everyone feels confident using ladders. But if you do, it can be a great way to clean those hard-to-reach windows without investing in new gear.

Before you put your foot on the first rung, make sure the ladder is in good working condition. You should also avoid using a ladder in bad weather. Aside from putting you at risk, it dramatically reduces your chances of doing a good job.

If you are nervous about using a ladder, having a friend, family member or relative on hand to hold the ladder and give you directions can make a valuable difference.

2. Use an extendable squeegee

If the mountain won't come to you, the proverb goes, then you must go to the mountain. Or, to put it another way, "buy an extendable squeegee".

These useful bits of kit have a telescopic pole, making it ideal for those hard-to-reach spots as well as everyday cleaning. Some extend far enough to reach third-floor windows without leaving the ground.

The key advantage to the extendable squeegee is that you don't have to set foot onto a ladder – a preferable setup for many people.

If you do plump for the extendable squeegee, make sure you clean from top to bottom. Going bottom to top or working at random can lead to streaks.

On a fine day, the air will dry the window for you. But if it needs a bit of help, you can cover the end of the pole with paper towels, newspaper or a microfibre cloth. Alternatively, you could use a broom or other pole.

3. Use a hose

Sometimes, speed is of the essence. At such times, spraying down the window with a hose will do the job. Just be aware that it could cause water marks that will have to be removed later. In other words, it's a quick fix and not a long-lasting solution.

4. Remove the window from the pane

If you've got sliding windows, you have the option of removing the window from its frame, cleaning it and then putting it back.

First, check for any screws or other locking devices that stop you removing the window. Before going any further, you need to remove these. You should also ensure the window isn't locked.

Once removed, you can clean your window however you like. Make sure to dry it off before putting the panel – and any components you removed – back in place.

5. Use a magnetic window cleaner

Magnetic window cleaners are a bit like Marmite. Some people swear by them. Others say they're the emperor's new squeegee.

Fitted with magnets, they clean both sides of the window when applied to just one side. In theory, you can get the outside looking as good as new without leaving the building.

Different models are available, so make sure you do your research before investing.

6. Hire a window cleaner

For many people, cleaning a hard-to-reach window is just one item on a lengthy to-do list. Sometimes, life gets in the way and the job keeps getting pushed back.

In this situation, why not hire a professional cleaner? They'll have the gear and skills necessary to do a good job – and chances are you'll be supporting a local business in the process. Win-win.

7. Self-cleaning glass

These days, you'd be hard-pressed to find a person in the UK who doesn't use labour-saving devices like washing machines. So, why does "self-cleaning glass" still sound like the stuff of sci-fi?

The answer is simple. Self-cleaning glass is expensive. It's not yet produced, distributed or installed at a large enough scale to be sold cheaply.

If you do have the money, however, it can be a great solution to the problem of cleaning hard-to-reach windows. That's because, well… the windows do the job for you.

Self-cleaning glass has a coating with two special qualities. First, it breaks down dirt and organic material when hit by ultraviolet rays. Secondly, it's hydrophilic, meaning rainwater spreads evenly over the glass. This stops streaks from forming.

It's important to note that self-cleaning glass still needs a bit of old-fashioned elbow grease – just not nearly as much as standard glass. For busy people with money to spare, it can take one chore off the list.

How to clean hard-to-reach windows

Whichever method you choose, there are some steps you should take to ensure you do a good job.

First, clean from top to bottom. Do it any other way and your windows will be covered in drips and streaks.

The other key piece of advice is to work in a steady, horizontal motion. Vigorous scrubbing will make the neighbours think you're working hard, sure. But it won't result in a sparkling pane.

It's best to clean windows on a clear, fine day. If it's too hot, the water will dry too quickly and leave streaks. If it's windy, dust and dirt can stick to the panes. And if it's rainy, well… you can figure that one out for yourself.

Microfibre towels are ideal for removing excess moisture and keeping windows clean. Unlike other types of cloth, they don't shed fibres or scratch the glass.

But perhaps the most important piece of advice we can give you is one that applies to so many domestic chores: little and often is better than once in a blue moon. A regular wipe-down will keep your windows nice and clean. The alternative is to leave the job and then spend the day scraping off inches of dirt.

Are conservatory roof replacements worth it?

simon@mydigitalhero.co.uk (Simon Edward) — Tue, 17 Dec 2024 11:37:30 GMT

Considering a tiled conservatory roof but having second thoughts? Learn 6 benefits that might convince you.

"Good fences", wrote Robert Frost, "make good neighbours" – and good roofs make good conservatories.

Why? Because above all else, a conservatory is a place to be. Yes, it can add beauty to your garden (and value to your home). But it's little more than a uPVC frame if it's not a space you want to spend time in.

Whether you use your conservatory to pot plants, get work done, write poems or entertain guests, comfort is all-important. And more often than not, the comfort of your conservatory will be determined in large part by its roof.

Traditional conservatory roofs are made of glass or polycarbonate. These roofs are far from useless. But too often, they make your conservatory noisy when it rains, nippy when it's cold and a tad too hot when it's sunny.

Luckily for you, there's an alternative. Tiled roof systems are great for controlling heat, light and noise. So, what are you waiting for?

Well, we know what the answer's going to be. A conservatory roof replacement isn't as cheap as chips. Sure. Work in the garden is disruptive. Sure! Nevertheless, we believe it's worth every penny.

Here are six reasons why.

1. It makes it comfortable all year round

Glass and polycarbonate are cost-effective materials for your conservatory roof. But they're not good at thermal control. In fact, we'd go so far as to say they're pretty bad .

We see it all the time. People's enjoyment of their conservatories is hamstrung by the fact that it's like an oven in the summer months and a fridge freezer in winter.

A replacement roof can give you better thermal control. But this doesn't just make your conservatory more comfortable. It also makes it more environmentally friendly as you won't need to blast a fan in summer or a heater in winter.

This second point is one key reason why a roof replacement is a sensible long-term investment. Not only is it much cheaper than replacing the whole structure, but it could also cut your energy bills in the future. Win-win!

2. It cuts down on noise

It's a fresh spring day. Birds are twittering. Your flowers are shining. Time for some quality time in the conservatory.

But this is Britain, remember, and you can never be sure it won't start raining. All of a sudden, your horticultural idyll sounds like cutlery being thrown into a scrapyard by a giant in a suit of armour.

That's if you've got a glass or polycarbonate roof. Tiled roof owners know no such pain. Their roofs are soft and muffling, making their conservatories pleasant places to be no matter the weather.

3. It reduces solar glare

Want to unwind in the conservatory with a book, phone or tablet? If your conservatory has a glass or polycarbonate roof, you'll need to take a pair of Ray-Bans with you.

Solar glare is another of those little things which can dampen your conservatory experience. By replacing the roof with a tiled affair, you get all the perks without having to squint.

4. It improves privacy and security

A conservatory should be a haven. If you feel exposed under glass, a tiled roof could be just the ticket. As well as increasing your sense of privacy, it can also make your conservatory more secure. Those tiles are far harder to break than glass or polycarbonate, after all.

Oh, and if a bird decides to take a moment on your roof, shall we say… well, you'll barely notice.

5. It requires less maintenance

Every homeowner knows that glass can be a nuisance to clean. Dirt builds up and before you know it, you're rolling up your sleeves and reaching for the nearest squeegee.

Tiles, by comparison, require far less maintenance. With glass and polycarbonate roofs, you'll probably spend most of your time in the conservatory looking forlornly at the roof and wishing it wasn't covered with dirt, seeds and bird droppings. Go down the tiled route, however, and these airborne imperfections will trouble you no more.

6. It adds style and character to your property

When getting your conservatory installed, you want to make sure it blends in with the style and character of your home. A tiled roof can play a big role here.

Tiles are available in a range of styles and finishes, from the traditional to the contemporary. This gives them far more aesthetic potential than a transparent glass or polycarbonate roof.

So, if you want to add a bit of oomph to your home, why not look at getting a tiled conservatory roof?

The bottom line

So there you have it: six reasons why a conservatory roof replacement is a good investment.

At the end of the day, these six reasons add up to one big reason: a better-quality roof will make your conservatory a place you want to be.

So, if you find yourself only using it now and then, a roof replacement could be the answer to your problems. We wish you many happy hours in your garden retreat!

It's clearly Christmas: 6 festive window display ideas for the home

dean@calderwindows.co.uk (Dean Page) — Mon, 09 Dec 2024 14:03:29 GMT

Want to turn your window into a winter wonderland this Christmas? Stick these 6 ideas in your scrapbook.

It's time to jingle our bells and hark our herald angels.

That's right: it's Christmas. And nothing says "Christmas" like some twinkly, sparkly, ding-dong-merrily decorations.

But you've already tinselled your tree, wreathed your front door and stuck a snow globe on every spare bit of shelf space. Where can you go next?

The answer: your windows.

Yes. Your windows are your Yuletide showroom. Deck them out with some suitably festive garb and you'll show everyone you mean Christmas business.

We're sure you're dreaming up ideas already. Here are a few of ours.

1. Give your Christmas tree top billing

Let's start with the simplest idea of all.

If your Christmas tree isn't next to a window, put it there. Job done.

It makes sense, right? The Christmas tree is the king, queen and chief elf of festive decorations. Perching it next to your window sends a clear message: "It's Christmas – and we're not going to miss a minute of it".

Of course, not everyone can shift their tree, furniture and life around at the drop of a hat. This idea is best reserved for those with large bay windows and plenty of floor space to fill.

2. Create a festive sticker display

Vinyl stickers are one of those quietly brilliant inventions – the kind you don't truly appreciate until you've seen them in action.

Well, perhaps "action" is too strong a word – but "see them in inaction" doesn't quite have the same ring to it.

See, the beauty of vinyl stickers is that they stick beautifully and stay stuck. But they don't use glue – oh, no. Vinyl stickers get their stick from the static charge on your windows. Clever stuff.

This makes them wonderfully flexible. Slap your vinyl snowflakes, stars or reindeer into place and they'll cling obediently onto the glass. But if you need to move them, you can – and they won't leave a sticky residue on the window.

This also means you can roll them up and store them until next Christmas. Bonus!

3. Embrace your inner graffiti artist

No, we're not suggesting you grab a can of spray paint and knock a few thousand off the value of your house. We're talking about that old classic: spray-on snow.

Good-quality snow spray won't leave a permanent mark on your windows but will leave a lasting impression on passersby. "Who cares if it's not a White Christmas?", your windows will squeal. "It's snow day every day in this house."

As far as designs go, you've more or less got three options:

Keep it simple with a tasteful snowy border.
Invest in some stencils and spritz some crisp snowflakes, Santas and the like. You could even make your own stencils if you want to save cash and get creative.
Go freehand. Embrace the chaos. Whip up a snowstorm of swirls, spots and spirals.

4. Give your windows a good chalking to

If you've ever given a presentation at work, you may have used chalk pens. They're great for office whiteboards because they leave a crisp, clear mark that can be wiped off easily with a dry cloth.

Well, they're not just for whiteboards. They're just as effective – and just as impermanent – on windows.

So, why not grab some white chalk markers and sketch your own Christmas window display? You could easily spend several hours ensuring every line and dot is in the right place. Or you could hand some pens to the kids and say, "Have at it". Up to you.

5. Celebrate Christmas by candlelight

There are two sides to Christmas.

One involves gloriously chintzy music, animatronic reindeer and bearded men in bright red suits. The other is all about delighting in the indoors, wrapping yourself in blankets and spending time with loved ones. It's a warmer, cosier – dare we say it, "hygge" – kind of Christmas.

We love both. But if you're more inclined towards cosy Christmas vibes, why not go all in with minimalism and turn your window into a candlelit festive feast?

It's as simple as it sounds. Grab a few heat-resistant trays, pop some candles on top and light them up. In an instant or two, your window will be bathed in a flickery, golden glow.

Safety first, of course. Always light candles on a heat-resistant surface and use proper candle holders. Don't leave them in reach of children and pets. And never – ever – let them burn unsupervised.

6. Turn on the twinkle

Do you love ambient lighting but are cautious around candles? We don't blame you.

The good news is that fairy lights can be just as gorgeous and don't involve naked flames.

There's a challenge here, though. How can you stick the lights around your window frame without making permanent marks? It's not like windows come with built-in fairy light holders.

You've got a couple of options:

Self-adhesive hooks: these are plastic hooks with a peelable strip on the back. Simply stick them around your window frame and you'll have a non-permanent hoist for your strings of lights. These hooks are often known as "Command hooks", after the brand that made them famous.
Suction hooks: these work similarly to self-adhesive hooks but stick to the glass itself. No glue required!

Either option would work indoors or outdoors. If you want to hang fairy lights on the outside of your windows, though, make sure you choose a set designed for outdoor use.

Want new windows this New Year?

Forget "New year, new you". We're sure the current you is perfectly fine.

Instead, why not give your windows some attention this winter?

For more than 30 years, Calder Windows has supplied and fitted high-quality windows in West Yorkshire. If you've had your eye on some sun-catching French doors , heat-trapping triple glazing or a gorgeous set of sash window replacements , it might be time to treat yourself.

Are integrated blinds right for you?

Sun, 01 Dec 2024 00:14:47 GMT

Integrated blinds have a number of advantages for homeowners. Discover all of them in our article.

Imagine a set of blinds that never needs to be cleaned and can be adjusted electronically. A set of blinds that can open and shut on a timer. A set of blinds that's sleek, uncluttered and attractive.

Is this what you're looking for? Then integrated blinds could be the right choice for you.

Integrated blinds have been on the market since the 1990s. In recent years, however, they've grown in popularity, both in domestic and commercial settings.

Essentially, they're blinds fitted between the panes of glass in a double-glazed unit. This keeps them out of harm's way, where they're no longer vulnerable to dust, dogs or toddlers.

They're versatile, able to be installed in windows, sliding doors, bi-fold doors and more. They come in different styles and colours. You get to choose whether to operate them manually or electronically.

At Calder Windows, we supply Uni-Blinds. For our money, these give you the good qualities we've mentioned in spades – and at an affordable price. Let's look at how they can enhance a set of bi-fold doors .

Why get integrated blinds installed in your bi-fold doors?

Bi-fold doors are a great way to connect house and garden, opening out the interior to let the exterior in.

In summer, you can throw open your bi-fold doors and enjoy a bit of natural air con – as well as an aesthetically appealing gangway into the garden.

Bi-fold doors also work well with balconies. Installations like these, however, call for privacy – and integrated blinds give it to you along with a host of benefits that regular blinds don't have.

The blinds act as an extra layer of insulation sandwiched between the two sheets of glass. This makes for a more energy-efficient solution, keeping the cold air out in winter and keeping cooling draughts inside in summer.

As well as providing a bit of extra comfort, this can help you stay on top of energy bills. It's a classic case of paying more upfront to garner savings down the line.

Integrated blinds also help with security. This is partly because double glazing is harder to break than single glazing. But it's also because the blinds themselves can't be damaged or stolen. On top of this, most bi-fold doors come with multi-point locking as standard.

The blinds are aesthetically versatile, coming in a wide range of colours, styles and finishes to blend in with your decor and match your personality.

But perhaps the best thing about integrated blinds is how little maintenance they require. Because the blinds are sealed in the double-glazing unit, you don't need to worry about your blinds becoming dirty, smelly or damaged.

Finally, they're safe. Unlike traditional blinds, integrated blinds don't pose any kind of threat to toddlers or pets.

What factors influence the price of integrated blinds?

Not all integrated blind systems cost the same. The exact price will depend on the following factors.

First, there's the question of material. Aluminium, for instance, costs more than uPVC or timber.

Then there's the size of the unit. The bigger the window or door, the more panels you need. Naturally, this will add up in price.

Integrated blinds can be operated by hand or motorised. The latter will cost you more than the former.

Finally, there are installation costs. You can install them yourself, sure. However, you may find that getting a professional to do the job will save you a lot of bother in the long run.

Can integral blinds be retrofitted into double-glazed windows?

Yes. So long as the gap between the panes is big enough, integrated blinds can be retrofitted in double-glazing units. This can be done with frames of any material.

How long do integrated blinds last?

One reason integrated blinds are a good investment is just how long-lasting they are. They're designed to last as long as the door or window itself.

Their durability is thanks to their design. Sealed off from dirt and damage, they can stay as good as new for years without much or any maintenance.

What are Uni-Blinds?

If you're interested in integrated blinds for your door or window, the next question is which brand to go for. Here at Calder Windows, we swear by Uni-Blinds.

Like all integrated blinds, they're installed within the double-glazed unit. But in our opinion, they do it better than the rest.

They're a doddle to keep in good condition. This doesn't just release you from the chore of ensuring your blinds are bacteria-free. It also means you won't have to pay for replacements. No broken blinds or tangled cords for you (hooray!)

As well as increasing privacy, Uni-Blinds give owners precise control over the amount of light and heat in the room. They can even be set to open and close on a timer. Done well, this can help lower your heating bills.

They're versatile, too. You can control them remotely with a button or remote control. Homeowners with smart home systems can integrate them with ease.

Finally, there's the aesthetics. Uni-Blinds are good to look at. This is partly because they have a sleek, uncluttered appearance and partly because you get to choose between different styles, colours and finishes.

All of these attributes combine to make Uni-Blinds a winning addition to doors and windows in both domestic and commercial settings.

Are Uni-Blinds right for you?

If you want an appealing set of blinds that are easy to operate and maintain, Uni-Blinds could be just what you're after.

Before you place your order, make sure you explore the full range of options. This will maximise your chances of getting a set of blinds that fit your requirements and your home's aesthetic.

Looking for a Uni-Blind installer in West Yorkshire? Here at Calder Windows, we supply and fit bi-fold doors with top-of-the-range integrated blinds. Get in touch today for a competitive quote – we'll be more than happy to help.

What your front door says about you

Fri, 29 Nov 2024 18:06:51 GMT

Could your front door reveal clues about your personality? Let's put on our psychoanalytical hats and find out.

In the property sector, people often talk about "kerb appeal". This is how your home looks to potential buyers passing by.

It rests on an assumption borne out by many studies. The assumption is that people pick up on signs of personality and professional status without even trying. Everything from the cut of your curtains to the way you trim your hedges could, it seems, communicate something about you.

Taking this to its logical extreme, could your front door alone say something about you? After all, it's the part of your house that gets the longest look from visitors of all kinds as they wait to be let in.

Not convinced? Well, we suspect that if you're reading an article about front doors, you probably care about your front door. And who are we kidding: it's not just functionality you're after. It's also aesthetics. And outside aesthetics often reflect what's inside.

From this point of view, your choice of front door is as revealing as your choice of hair products or the car you drive.

Well, it could be a load of old baloney – but it's fun to think about. And who knows? There could be something in it. So, without further ado, what does your front door say about you ?

Colour

They say that your favourite colour says a lot about you – although it could reveal as much about who you want to be as who you are.

A red front door, for instance, communicates decisiveness, assertiveness and drive – a very different personality profile from someone with a door in a soft pastel colour.

Of course, these days, the colour of your door isn't just the colour of the door itself. It can also be about the colour of your "door furniture": knockers, letterboxes and numbers.

Brass house numbers gleam in the sunlight. They're classy. They suggest a taste in house design that's not afraid to show off.

House numbers in chunky, wiry or comic-book fonts, however, show you're not afraid to be quirky – in fact, you revel in it.

It's incredible to think what signs your delivery driver is picking up about you simply from the colour of your front door…

Style

Ah, style. Depending on who you are, style can sit on a spectrum that ranges from "hobby" to "pathology". Wherever you sit, your style choices communicate a lot about you. It's as inevitable as people making assumptions based on your name or accent.

Front doors are no exception. A heavy timber door implies an old-fashioned rustic sensibility. Within, the smells of roast rabbit, leather polish and sheepdog. The wardrobes teem with Barbour jackets, fleeces and walking boots. Even in the city, this is a home that screams "countryside".

Other people will go for a classic front door. This style is hard to define, but if you imagine the door to No. 10 Downing Street, you're in the right ballpark.

These kinds of doors have a lot of range, but they all bespeak respectability and tradition. No airs and graces for you (although that brass knocker is a bit on the fancy side). You don't want to stand out. Rather, you want to take your place alongside your neighbours, quietly upholding old-fashioned values.

Your choice of glass could be revealing, too. Compare a stained glass window to a bold sheet of coloured glass, or frosted glass to a simple clear pane.

Each one says something about how you want to present yourself – be it outgoing, introverted or artistic. All of that from just a front door… The mind boggles.

Furniture

Door furniture is to your front door what accessories are to your outfit. They may seem like afterthoughts, but they can really tie the whole thing together.

Just as a well-chosen bracelet or pendant can turn a run-of-the-mill outfit into a head-turner, so a letterbox, knocker or house number can level up your front door game.

Imagine you turn up to a dinner party. It's your first visit to this house. There, in the middle of the front door, is a bronze knocker in the shape of a lion's head.

What does this tell you about the night ahead? Are they animal lovers? Do they love to make an impression? Are they, um, rich? It's just one detail, sure. But it sparks the imagination.

The same goes for door handles. Knobs and levers have different taste notes, so to speak. A knob is self-consciously retro, a lever more everyday.

So, if you're getting a front door replaced, don't shy away from thinking about door furniture. "The door devil," they say, "is in the details."

Material

Finally, there's your choice of material. This, too, could say something about you and your home.

A steel door could suggest utilitarianism, graft and a scientific mind. Timber connects you to the soil. uPVC and composite doors suggest a willingness to embrace the new.

There's no right material for a front door. Each has its advantages and disadvantages. But as well as these, it can also give a glimpse into your personality, your priorities and even your way of life.

What if your front door is past its best?

If eyes are the windows to the soul, then a front door is the eye of your house. It tells visitors and even passersby about your personality and your priorities.

Or it could just tell them that, well, you need a new front door. After all, many people buy homes with a front door already in place. Sure, you'll get around to replacing it one day, but until then, it's doing just fine.

We get it. But a new front door can add a splash of colour and class to your home – not to mention improve your security.

So, if you're looking for a front door fitting service in Yorkshire, get in touch with Calder Windows today. We'd love to talk you through your options and fix you up with a front door that suits you .

How to make your conservatory feel like part of your garden

Mon, 18 Nov 2024 07:14:19 GMT

A conservatory can enhance your home. But how do you make it part of your garden? Find out in our guide.

A conservatory can provide a cosy setting for pretty much any activity. It doesn't matter whether you're potting plants, entertaining guests, playing a board game or taking a work call – a good conservatory is a room you want to spend more time in.

But conservatories differ from household rooms in one significant way. They bridge the gap between the indoors and the outdoors. They're transitional spaces between home and garden.

Because of this, it's essential that your conservatory feels like part of the garden. The last thing you want is an incongruous building plonked down on your lawn.

How, then, do you blend the two? The answer has more facets than you might have thought. It covers everything from the design phase to the heating, from the ventilation to the glass you use – and plenty more along the way.

So whether you're getting a conservatory installed for the first time or renovating an existing structure, we hope this article helps you make your conservatory feel like part of your garden.

1. Decide what it's for

This might sound obvious, but you'd be surprised how many people get a conservatory without knowing what they'll use it for.

It matters because the function of a conservatory determines its layout, its layout determines its furnishings and its furnishings determine how well it blends into the garden.

So, before you commit to a design, make sure you know whether it's primarily a space for gardening, entertaining, relaxing or some combination of the three. This will help you make the many smaller decisions that will follow.

2. Plan, plan and plan some more

Do you have a vision for the furniture in your conservatory? Are there particular plants you want to grow? Then you need to plan your conservatory in detail.

What you put in your conservatory will determine the floor plan and the structure's proportions. The alternative is to get an off-the-shelf conservatory that sits in your garden like a white elephant with a sore thumb.

3. Use plants creatively

One of the easiest and most versatile ways to make your conservatory feel like part of the garden is to fill it with greenery.

The outside, too, can be a showcase for tall plants, small trees, climbers and vines. This helps bridge the gap between inside and out.

When it comes to plant life in and around your conservatory, the sky's the limit. You know what's in your garden and what your plans are for the future. Have fun exploring how your conservatory can complement these.

4. Choose your flooring carefully

Watering plants on the regular? You're going to need a floor that can withstand spillages.

A popular choice for conservatory flooring is paving. Matching the interior and exterior paving helps smooth the transition from inside to out.

This is just one option, however. You can go for anything from easy-clean laminate to vintage tiles. Your choice of material and design can be critical in making your conservatory feel like part of your garden.

5. Invest in ventilation

The ideal conservatory is an environment you can sit in all year round, watching the changing of the seasons from your see-through sanctuary.

But to be comfortable, you need good ventilation. Hot air builds up in glass houses and needs to be released. For this reason, you should invest in roof vents to maintain a cool and pleasant atmosphere.

These vents can be manually operated or automated. This second choice is ideal if you're often away from home.

6. Think heating

As well as ventilation, good heating is essential for a homely garden room – and essential, too, for growing the kinds of plants you want.

If you're passionate about tropical plants, for instance, your heating needs will be very different from a conservatory built to grow hardy winter plants. Most people opt for something in between. It all depends on what you want in your conservatory and how this greenery will blend with your garden flora.

Conservatories can be heated in different ways. Underfloor heating has the key advantage of being out of sight and out of mind – but it does limit the kinds of flooring you can get installed.

7. Get a solid tiled roof

For your conservatory to truly be a part of your garden, it needs to be somewhere you want to sit, whatever the weather.

Achieving this combination of robustness and cosiness is much easier when you have a tiled conservatory roof – not least because it will help with insulation and weatherproofing.

But this kind of roof can also help you blend the appearance of your conservatory with the garden. They add a rustic touch – one that can be personalised by choosing colours that work with the plant life in your garden.

8. Add bi-folding doors

What better way to bring the outdoors in than with a set of floor-to-ceiling bi-folding doors ? You can swing them open to let the fresh air in and shut them when you need warmth and dryness.

One of the best things about bi-fold doors is that they give you a wide-angle view of the garden even when the weather's bad. This makes it part of your garden all year round – not just when the sun's shining.

Coloured glass is an option. But for our money, neutral glass is best for a conservatory. It maximises the views and the amount of natural light pouring in.

Conclusion

Whatever you plan to use your conservatory for, you want it to feel like part of the garden. Taking these eight tips into account can help you get there, whether you're buying your first extension or getting some renovations done. We wish you all the best in your journey.

Is your home prepared for winter?

Fri, 08 Nov 2024 14:00:29 GMT

Does your home feel like a freezer in winter? Learn 3 quick fixes and 4 long-term solutions to beat the chill.

When the sun's shining and all you want to do is play Frisbee, it's easy to ignore the nagging problems with your home.

But then winter strikes and these problems come back to bite you. Draughts. Damp. The kind of chill that can cut through the thickest blankets and the woolliest of jumpers.

The good news is that you don't have to suffer through it. There are plenty of quick fixes you can implement to stave off the worst of the winter blues. And if you have the budget and time, you can go the whole hog and fix the issues for good.

Seven ways to prepare your home for winter

Quick fixes

Running out of time? Strapped for cash? Perhaps it's midwinter already and you're reading this under a 15-tog duvet.

Don't fret just yet. Here are some quick tips to help you beat the cold and damp. All are easy to implement and quite affordable – if not completely free.

1. Buy draught excluders

In an ideal world, our homes would be as tightly sealed as a jar of pickled onions. However, it's more likely that you have a few draughty spots – especially if your house is on the older side.

We're looking at you, windows and doors. If you have an old, leaky window frame or a gappy front door, it will only suck warm air out, blow cold air in and make your central heating work harder.

That's why it's worth investing in that old favourite: the draught excluder. This is a kind of long, snakey pillow. Place it across the draughty gap and it will help stop cold air in its tracks.

Draught excluders are surprisingly effective – and surprisingly cheap. You'll find them online from four pounds and up.

2. Bleed your radiators

Radiators need TLC. If you leave them alone for too long, they'll start to heat unevenly. This is because air gets trapped in the system and creates gaps that hot water can't reach.

If your partner needs attention, you buy them a bunch of flowers. If your radiator needs attention, you bleed it. This isn't as violent as it sounds.

When you bleed a radiator, you release this built-up air and allow water to flow freely. And all you need is a radiator key and a cloth to catch the inevitable drips.

It's a quick job – but it could save you from a cold winter and an even frostier heating bill. Just make sure your radiators are completely cool before you begin the bleed.

3. Clean your gutters

Cold isn't the only ghoul that haunts our homes in winter. Damp does too – and it's just as ghastly, if not more so.

Damp can lead to mould. And mould can cause all sorts of health issues, ranging from coughs and sneezes to severe allergic reactions and respiratory problems.

Tackling mould should be near the top of your winter agenda. And there are several steps you can take to mitigate it, including running your central heating and investing in a dehumidifier.

These are good ideas – but they cost money. So, if you're strapped for cash, your gutters are a good place to start.

When leaves and other gunk build up in gutters, it can affect drainage and make damp problems worse. Get up there and give them a good clean. If you're lucky, you might just see those damp spots disappear.

Long-term solutions

These fixes need a little more time – and a little more investment.

They're well worth it, though. The amount you'll save on heating bills means you may well make your money back. And, of course, you can't put a price on comfort.

4. Get triple glazing

According to government figures, nine out of 10 homes in the UK now have double glazing.

Hurrah for that. Compared to old-school single-glazed windows, they're very energy-efficient. This means less heat loss, as well as lower heating bills because your boiler won't have to work as hard.

However, if your home is hard to heat – or your windows are past their best – you might benefit from tripling up.

A good triple-glazing system will beat double glazing hands down. Our extra-thick triple-glazing units, for instance, are around 40% more energy-efficient than standard double-glazed windows.

The fact you'll have crisp, attractive new windows is just the icing on the cake.

5. Fit a composite door

Doors, like windows, have seen a raft of improvements in recent years.

Modern composite doors are a darn sight more energy-efficient than their old wooden cousins. That's because they're fitted with an insulating layer that helps trap heat and keep cold air out.

And that's not the only benefit. Unlike wooden doors, composite doors will never rot, warp or discolour. So, investing in a new door means feeling the benefits for many years to come.

Porch feeling a little breezy? Invest in a composite door. You won't regret it.

6. Upgrade your insulation

You could buy every draught excluder on Amazon. If your home isn't insulated – or your insulation is out of date – then you'll still suffer through every cold snap.

Insulation isn't cheap. If you live in a three-bedroom semi and you want to fit loft insulation, you can expect to pay around £1,000. For roof insulation, it's about another grand. For cavity wall insulation, you'll fork out between £1,000 and £2,000.

As you can see, the costs quickly add up – but so do the savings. Cavity wall insulation alone can save you around £245 on your energy bills. This means it should pay for itself in a few years.

And grants are available if your home meets certain criteria. Check GOV.UK's page about the Great British Insulation Scheme to learn more.

7. Invest in a new conservatory roof

Conservatories are lovely in summer. But when the colder months roll around, they often become no-go zones.

This is a terrible shame, as far as we're concerned. What's the point of having a garden room if it gets as chilly as your garden?

Here's the thing. Conservatories don't have to be cold. Give yours a little structural spruce-up and it could soon become your favourite room – no matter the season.

As with homes, the key is insulation. In the case of conservatories, much heat is lost through the roof. But with a modern conservatory roofing system, you can drastically reduce this heat loss and enjoy a swathe of other benefits to boot.

Here at Calder Windows, we're registered installers of SupaLite: a thermal conservatory roof system that's easier to maintain, cuts down on noise and helps maintain a comfortable temperature all year round. What's not to like?

Calder Windows is a trusted team of window and door specialists based in West Yorkshire. We've supplied and installed high-quality glazing products for more than 30 years. Want to see how we can transform your home? Get in touch to discuss your project with our friendly experts.

4 classic door styles – and how to nail the vintage look today

Fri, 01 Nov 2024 09:09:39 GMT

Looking for a timeless door style with modern functionality? Explore 5 styles in our guide to vintage looks.

There's an old Yorkshire saying: "Put wood in 'ole." It means, quite simply, "Shut the door". In the old days, you see, the vast majority of doors were made out of wood.

Today, the market is flooded with options. Traditional timber is still an option, but you can also go for uPVC or composite doors. Your doors can be decked out with patterned glass, handles, knockers and numbers.

Some door styles scream "now". But many homeowners want a homely, vintage look – one that makes their home look like it's been ripped from the pages of a magazine on period living.

Vintage door styles, however, come with their own problems. They tend to require an onerous amount of upkeep, and they don't score highly for thermal efficiency – something that's bad for the planet as well as your wallet.

If only there were a way of combining those timeless looks with timely technology… Newsflash: there is.

Yes, homeowners can nail a variety of vintage looks without condemning themselves to a life of maintenance and high energy bills. In this article, we explore four of the best.

The classic classic

This is the most nebulous of vintage door styles. It's, well, a door. Close your eyes and picture a front door – you're probably seeing one of these. It's not rustic. It's not industrial. It's just a solid, attractive door, perhaps fitted with decorations (or "furniture" as it's known in the trade).

This kind of door is the go-to for many homeowners. It conveys modest elegance and a lack of pretence. But that doesn't mean it's lacking in personality.

Get yourself a classic classic and you can easily customise it with patterned, coloured or frosted glass. You can get a handle in silver or gold and decide where it goes. You can get your house number in a font that matches your personality.

It's the very simplicity of this design that makes it so versatile. After all, the more flamboyant you go, the less room you have to experiment. With the classic classic, you get an unfussy vintage look that can be subtly tweaked to meet your requirements.

If you choose this style, your best bet is to go for a uPVC door . Compared to wooden doors, these are built to keep out noise and withstand the vicissitudes of British weather. Ours come with multi-point locking for peace of mind. What's more, a reputable dealer like Calder Windows will furnish you with a warranty lasting 10 years or more.

Decorative glass

Do you want your hallway, kitchen or other domestic space to be flooded with coloured light when the sun's out? Then you might want to get a door fitted with coloured glass.

If this is the style you're after, you can go for uPVC or a composite door. Composite doors are built to last. They're manufactured in such a way that you don't need to worry about repainting or peeling paint.

Decorative glass is a world unto itself. It can be as simple as hatched black lines on clear glass or as complex as a cathedral window. In either case, you can get the look you're going for with a modern uPVC or composite door. Vintage, you see, doesn't have to mean old.

Cottage doors

Nothing conveys comfort and class like a vintage cottage door. You know the kind we mean. It's rustic. It's homely. The sound of the knock is as timeless as the thwack of leather on willow. And above all, it has a beautiful grain.

Some vintage styles call for smooth surfaces. But the classic cottage door is all about beautiful imperfections – those knots, black spots and crevices that link the door to its woody origins.

Solid oak doors are on the market and they have cost-effectiveness on their side. They're cheaper, at least, than composite doors. So why choose composite over good old oak?

The answer is maintenance. Oak has a way of weathering and warping. If you're fine with that, then go oak. But if you want the same look with a bit less elbow grease, a composite door is the way to go.

Art Deco

Art Deco doors are a minimalist's dream. Those sleek, elegant, industrial lines holding big panes of clear glass have a cool, unfussy look that could be from 1860 or 1960.

Despite their industrial origins, Art Deco doors blend seamlessly into domestic settings. Aesthetics aside, they're a great way to bring more natural light into your home.

And, let's face it, they're a real statement piece. No visitor is going to fail to admire your heritage-style doors.

But like the other vintage doors we've mentioned, Art Deco doors have a built-in problem. Those steel frames are pretty bad at keeping the heat in. At a time when sustainability is a priority – and energy bills are high – you might be in the market for an alternative.

Thankfully, you can get heritage-style doors that combine the aesthetic of Art Deco with modern standards of thermal efficiency. Win-win!

The same goes for French doors and bi-fold doors , whether you plump for a sleek frame or something on the chunkier side. All of them can be secure, robust and long-lasting: the perfect marriage of vintage and modern.

Why choose modern doors?

Styles become vintage for a reason. They're still points in a turning world, outliving fads and fashions.

But old-school doors were built in line with old-school standards of durability, security and thermal efficiency. They simply don't meet modern expectations about what a door should do.

Luckily for homeowners, the industry has listened and developed doors that combine timeless aesthetics with modern functionalities. Whatever style you're after, you can nail that vintage look without sacrificing quality.

5 real-life UK conservatories that make creative use of space

Mon, 28 Oct 2024 10:58:11 GMT

Conservatories can add a touch of sophistication to any property. Explore 5 real-life examples from the UK.

Conservatories are a surefire way to add a touch of class to your home and garden. Whether you go for a traditional Victorian model, a contemporary aesthetic or something in between, you can create a whole new space, filled with natural light and garden views.

Part of the appeal is that the space itself is flexible. Conservatories can be gardening stations, home libraries or places where you entertain guests. It all depends on the furnishings you choose and how you use the space.

Questions of furniture, flora and function are asked by all conservatory owners. Some people, however, take things to a whole new level.

Yes, a conservatory can be a real statement piece, reflecting the taste, wealth and personality of its owner. And so often, these qualities are reflected in the use of space as much as the external structure.

In this article, we look at five real-life UK conservatories that make the most of their space.

1. Rosie Copeland's colourful conservatory

Not every artist has an artistic home. Some put all their energies into their paints, clay or plaster. But others invest their homes and gardens with the same visual imagination that drives their work.

Rosie Copeland is one such artist. Specialising in still lives, landscapes and life studies, she lives in a redesigned, refurnished former vicarage in south London with her husband and three children.

Rosie worked with interior designer Tamsin Saunders to reimagine the house and garden. Early in their collaborative process, Tamsin told Rosie, "You love colour… You'd never paint an all-grey picture. So, why should your home be any different?"

This conversation pushed Rosie towards a more adventurous palette – one that's displayed to subtle but impressive effect in the conservatory.

Conservatories are known for bringing the garden into the home. Rosie and Tamsin reflected this ethos by painting the tall doorframes leaf-green and fitting them with rustic wooden blinds.

The result is a cosy countryside environment tucked away in south London.

2. Arboreta's oak oast-style conservatory

Spend any time in Kent and you're bound to see an oast, also known as an "oast house" or "hop kiln". These buildings are used for drying out hops – an essential step in the beer-making process.

But oasts aren't just functional. They also have a striking aesthetic: pointed, almost pyramidal roofs atop round brick buildings. It's no exaggeration to say they can look like a cottage from a fairytale or fantasy novel.

This quaint aesthetic has been embraced by conservatory designers Arboreta. They built a mini oast with a tile roof and a green oak frame made by hand in Wales.

This quirky commission is an example of how versatile conservatories can be. It's not all Victorian steel and glass – when it comes to conservatory design, the only limit is your imagination.

3. The Khora Architectural Dome

It's hard to overstate the importance of Victorian conservatory aesthetics on modern design. After all, the Victorian era could well be called the Age of the Conservatory: a time when manufacturing methods meant conservatories could be manufactured, supplied and installed on a large scale.

The Khora Architectural Dome is a steel-framed garden room in London that takes inspiration from Decimus Burton's Palm House at Kew Gardens. This wrought-iron creation, filled to the rafters with tropical plants, has dazzled visitors since the 1840s.

Khora's contemporary version has a similar capacity to dazzle. At the very least, it dazzled judges at the RHS Chelsea Flower Show, who gave it the Director General Award for best trade stand and the Five Star Best Stand award.

4. Rose Uniacke's rustic conservatory in west London

When it comes to interior design, Rose Uniacke knows her onions. Her clients have included the Beckhams and perfumier Jo Malone.

But this busy schedule hasn't stopped her from turning her west London Georgian Revival villa into a remarkable home and garden.

When she and her husband, David Heyman, bought the house in 2007, it was clear the property needed a lot of work. Rose embraced the challenge, working with Belgian architect Vincent Van Duysen to make a home that reflected her and David's taste and personality.

One of the most remarkable features of the renovated home is the deluxe yet rustic conservatory that Uniacke calls the "winter garden".

Today, Rose likes to use the winter garden as a spot for reading and arranging flowers. It's also where the family has its meals, sitting around a French steel table.

Getting to this point required a lot of work – and most of it involved subtraction rather than addition.

The glass roof was taken off, creating more space in the room, and replaced by a bespoke Victorian-style skylight. The original wood rafters were cleaned and left exposed. The walls were stripped, with the brickwork underneath adding a farmhouse vibe.

The result is cosy yet luxurious, retro yet modern, rustic yet fit for modern life – the perfect place for orchids, tropical plants and climbing vines to grow.

All in all, the winter garden is another great example of the stylistic possibilities of conservatories – and how so much of their charm derives from a creative use of space.

5. Rooftop conservatory, Hampstead

Last but not least, a conservatory that answers the age-old question: what do you do if you don't have a garden? Answer: you put your conservatory on the roof.

Conservatory firm Apropos installed a powder-coated aluminium conservatory on a Hampstead roof. Now, its owners get the best of both worlds: sweeping views of the city and an intimate rooftop space where plants can grow.

It all goes to show that when it comes to conservatories, the sky's the limit – and the creative use of space is key.

Busting myths about aluminium windows and doors

Mon, 21 Oct 2024 10:21:36 GMT

Unsure about buying aluminium frames for your windows or doors? Join us as we debunk 9 persistent myths.

Aluminium has long been the material of choice for windows and doors in commercial premises – and increasingly in domestic settings, too.

Nevertheless, aluminium has a surprisingly spotty reputation. Perhaps it's memories of early aluminium products that were functional but a little cold – both literally and aesthetically. Or perhaps there's a lingering sense that metal is less homely than wood.

Whatever the reason, we're here to tell you that aluminium is a great choice for window and door frames. It's durable, attractive, customisable, secure, environmentally friendly, cost-effective and easy to maintain. That's quite the list of attributes!

In this article, we debunk nine persistent myths and misconceptions about aluminium frames. We hope it encourages you to consider aluminium when you next get a window or door replaced or installed.

Myth 1: aluminium frames aren't durable.

The facts: aluminium frames may be slim and light but they're far from feeble. In fact, a good-quality aluminium frame can withstand hurricane-force winds.

Not only that, but they can last upwards of 45 years. That's longer than the average lifespan of a rhinoceros.

And they don't just last a long time – they stay crisp and rust-free for a long time, too. This is all thanks to advanced powder coating technology that stops the metal from corroding.

Myth 2: aluminium frames are ugly

The facts: beauty is in the eye of the beholder, of course. But we strongly suspect that most people would look at a contemporary aluminium door or window frame and say it was at least as attractive as a uPVC or wood equivalent.

Aluminium frames can be modern and elegant – and they're versatile, too. They can blend into any style and painted any colour. They can even be given matte or gloss effects.

Naturally, there are cheaper and less attractive options on the market. But find a good provider and you can invest in frames that reflect your personality and match the style of your home.

Myth 3: aluminium frames are easy to break

The facts: aluminium frames provide excellent protection against burglary and are actually sturdier than other types of window frames. If you still need a bit of reassurance, you can always fit an aluminium frame with an extra locking system.

Either way, aluminium door and window frames give you the peace of mind every homeowner needs.

Myth 4: aluminium windows need hardwood subframes.

The facts: some aluminium windows are fitted to hardwood subframes – but that doesn't mean hardwood is a necessity when getting new frames installed. In fact, there are plenty of direct-fix window systems that remove the need for hardwood subframes.

Myth 5: aluminium frames aren't environmentally friendly

The facts: aluminium frames are fully recyclable – as are most types of glass. That means a window in an aluminium frame is 100% recyclable.

The misconception that they're bad for the environment comes from the early days of aluminium frames. When they were introduced in the late 70s, they were cold to the touch.

This was because they didn't have today's thermal breaks: those polyamide or expanded polyurethane barriers that separate the internal and external faces of the material.

Thermal breaks provide insulation, making aluminium frames more energy-efficient. Some are fitted with gaskets for extra insulation.

Myth 6: aluminium frames are difficult to maintain

The facts: aluminium doesn't rust. It's an unattractive home for termites and other insects. It can withstand mighty winds. And it doesn't flake, rot or peel off easily.

All of these qualities make aluminium extremely easy to maintain. Just wipe it gently with a mild detergent and warm water. Simple!

Myth 7: aluminium windows are a commercial product

The facts: aluminium window frames have been popular with commercial designers and architects for decades. This leads some people to think that aluminium frames are strictly business.

In fact, aluminium window and door frames are an increasingly popular choice for homeowners thanks to their durability, low maintenance and energy efficiency.

Part of the appeal is that aluminium frames can be installed in a wide variety of window and door types. In the world of windows, for instance, you can get aluminium casements, sash windows, sliding windows, bay windows, bow windows, tilt-and-turn windows… The list goes on.

So, if you're looking to get window or door frames replaced or installed in your home, make sure to explore your aluminium options.

Myth 8: aluminium frames are expensive

The facts: the initial cost of aluminium frames can be higher than their uPVC or composite equivalents. However, their longevity and energy efficiency make them more cost-effective in the long run.

With aluminium, you're not just paying for a functional material. You're paying for a product that will save you time, money and effort.

Myth 9: aluminium windows condensate

The facts: this one requires a little explanation. Aluminium windows do condensate – but only as much as any other glazing.

You see, no window can eliminate condensation. You should raise an eyebrow if a window fitter tells you otherwise.

Nevertheless, aluminium frames are low on condensation. The designs have come a long way since the 1970s and 1980s. Choose aluminium and you can be sure you're keeping condensation to a minimum.

Conclusion

So there you have it – nine persistent myths about aluminium door and window frames and the truth behind them.

We hope this article encourages you to consider aluminium frames as an option if you're looking to replace or install new frames. They're elegant, durable, easy to maintain and thermally efficient. Not only that, they unlock creative possibilities for your home. Make sure not to sleep on aluminium!

Halloween window decorations: 13 spooky ideas

dean@calderwindows.co.uk (Dean Page) — Fri, 11 Oct 2024 08:16:08 GMT

Are you getting your home ready for Halloween? Explore some simple, creative window decoration ideas.

When spooky season is nigh, it's time to make your house look the part.

Whether you're planning on throwing a haunted soiree or want to give the trick-or-treaters a treat, Halloween decorations can be as fun as they're creative.

And like all holiday decorations, it's up to you how far you want to take things. You can make your house look like the Addams Family mansion, a witch's cottage or anything in between.

The driveway and front door tend to be the star attractions. But this year, why not give your windows a face-lift? Here are 13 ideas to up your Halloween window game.

1. Snow spray stencils

On special occasions, it can be tempting to buy all new decorations. But why not repurpose some snow spray from your Christmas decoration box? This Halloween, use it to spray stencils of ghosts on the windows for a late-October chill.

2. Inflatables

Inflatable ghosts, skeletons, witches and the like are Halloween staples. But did you know you can use them to spook up your window, as well as your driveway and porch?

You can buy skeletons and arrange them to look like they're climbing the walls or through the windows. You can even get a ghost that's half inside and half outside, appearing to crash through the window.

3. Window clings

Window clings are a type of adhesive-free sticker that can be applied to glass or plastic.

There's a huge range of options out there, but one of our favourites is the eerie image of witches hard at work at their cauldrons.

Kids love window clings and you can be as minimalist or maximalist as you like.

4. Light-up decorations

Gift stores often stock battery-powered spiders, pumpkins and the like. These are fitted with suction cups that hang to the window.

5. Leave a message for trick-or-treaters

If you're happy to entertain trick-or-treaters, why not level up with a message in the window? It could warn them of the horrors lurking within or simply say, "Boo!"

This can also be a friendly way to send kids on to the next house if you're not in the mood for giving out sweets.

You could use a message board, LED board, stickers, calligraphy, glow-in-the-dark paint… As with all these ideas, the only limit is your imagination.

6. Paper silhouettes

On a budget this Halloween? Get crafty with paper silhouettes.

These are super-simple decorations that kids love to get creative with – and unlike some of the decorations you see, they're easy to make and require just a few supplies. You can draw your design with black paint on paper or simply cut them from black paper.

Oh, and let's face it – Halloween can be a wasteful time of year. Paper silhouettes are a great alternative that can either be put in the recycling or used again next year.

7. Lace curtains

If you've got a taste for old-timey haunted houses, lace curtains are the way to go. A Gothic fringed curtain over the windows is sure to scream, "Witch within!"

As with all these suggestions, you've options. A grey lace curtain with skull designs or a plain black gauze are just two of our favourite ideas.

8. Boarded-up windows

Want your home to look haunted? You could do worse than board up the windows.

Tack lightweight boards around the window – or, if you're worried about leaving marks, nail the boards to a separate frame and hang it over the window.

However you do it, you're sure to be a spooky stand-out in the neighbourhood.

9. Glow-in-the-dark eyes

Are those eyes in the window? Are they glowing in the dark? Are they… blinking at you?

Gift shops sell battery-operated glow-in-the-dark eyes that look like ghosts staring out at the world of the living. They look great on their own or as part of a bigger display.

If you're on a budget or just in the mood for some arts and crafts, you can also make eyes for your window frame out of paper or card.

10. Origami bats

No Halloween is complete without bats. The market is flooded with the plastic variety – but why not make your own out of origami? These can be stuck to the window with double-sided tape or hung from strings.

11. Reaching hands

What could be spookier than monstrous hands that seem to be reaching out of the window? These can be bought from gift shops, toy shops and other outlets.

12. Pumpkins

Keep it simple and classic with a pumpkin in the window. One of the great things about pumpkins is the creative possibilities they present. You can carve anything from eyes, nose and mouth to a terrifying scene ripped straight from the movies. Plus, they're biodegradable – something worth bearing in mind at a time of year that produces a lot of plastic waste.

A cute twist on this idea is to get (or make!) wool pumpkins. These are available on Etsy and elsewhere.

13. Go minimalist, go maximalist

Whatever decorations you choose, there are two main styles of Halloween display: minimalist and maximalist.

If you have a taste for the low-key and elegant, you could limit yourself to a stained glass window hanging, a moon-shaped mirror or a banner of bats.

If, on the other hand, you want to make an impression, you can throw in everything but the kitchen sink: bunting, inflatables, stickers, calligraphy… With so many options at your fingertips, there's no reason not to think big.

As with all decorations, it's worth trying to minimise waste. Try to avoid single-use plastic products, or complement them with decorations you can hang up year after year. DIY projects are another great way to bring down your costs and carbon footprint in one fell swoop.

What is FENSA and what does it mean for you?

Mon, 30 Sep 2024 16:14:45 GMT

Getting a window or door replaced? It's worth using a FENSA-approved installer. Learn why in our guide.

The marketplace for windows and doors has never been more saturated. This has benefits for consumers. However, it can always make it hard to answer that crucial question: "Is this installer going to do a good job?"

There are telltale signs, of course. You can look for positive online reviews. You can look to see if the firm is well-established. You can ask your friends, your colleagues, your hairdresser.

But even if you've found these things out to your satisfaction, you still might want reassurance. What you want is an external standard – a third-party stamp of approval to show that this installer is trustworthy.

This is where FENSA comes in. FENSA is a government-authorised scheme that aims to improve window and door replacements in the UK.

It does this by giving installers a professional stamp. If your installer is FENSA-approved, you can be sure it's compliant with building regulations and registered with the council. It also shows that its installations are energy-efficient.

What's more, if the certificate was issued after 6 June 2016, it demonstrates that the installer's warranty is insured.

Without these reassurances, you may find yourself spending a lot of time and money on a subpar job.

At Calder Windows, we're FENSA-approved. Once we've completed an installation, we can issue a certificate of quality: proof of a job well done and one less hoop to jump through should you come to sell the property.

Are FENSA certificates a legal requirement?

Replacement windows and doors are legally required to be compliant with building regulations. Any installations made since 1 April 2002 need either a valid FENSA certificate or a building regulations certificate. In the case of doors, FENSA approval depends on the amount of glazing in the door.

How long does a FENSA certificate last?

Typically, a FENSA certificate lasts for the lifetime of replacement doors and windows. It also gives you an insurance-backed guarantee, typically lasting 10 years.

Do you need a FENSA certificate to sell a house?

Before you sell a house, you either need a FENSA certificate or a building regulations certificate to demonstrate that your doors and windows are compliant with building regulations. There's also the possibility of the buyer taking out FENSA insurance.

Can you fit new windows and doors without a FENSA certificate?

Yes. You don't need a FENSA certificate to fit new windows or doors. If you're working with an installer, however, it's desirable as it shows the job will be done in line with building regulations. It will also mean you don't need to get your doors and windows checked by a surveyor should you come to sell the property.

Are FENSA certificates required for doors?

Yes, doors as well as windows need to be FENSA-approved. However, if a door has less than 50% glazing, it's exempt.

Do you need FENSA approval for DIY jobs?

If you've got the skills, you can fit your own windows and doors. However, they will need to be checked by a conveyancer should the property go up for sale.

Can a FENSA certificate be issued retrospectively?

If you had replacement windows and doors installed but weren't issued a FENSA certificate, you can get FENSA approval retrospectively. In this situation, you need a Retrospective Building Regulation Compliance Certificate from your Local Authority.

Are there exemptions to the FENSA scheme?

New builds, extensions, commercial premises and listed buildings all fall under the purview of the Local Authority rather than FENSA. You also don't need FENSA approval for doors with less than 50% glazing or for non-habitable areas such as garages.

Why do industry accreditations matter?

Whether you're a homeowner, a business owner, or both, you're sure to notice one thing when shopping for windows and doors: you're spoiled for choice.

We live at a time when the consumer market is saturated with choice. Navigating the endless aisles of eCommerce can be disorientating and leave you feeling less clued up than before you opened your browser.

How do you know that an installer is going to do a good job? You can look for online reviews – but we all know that one-star reviews are often the product of a bad mood rather than a fair representation of a company's services. Or you can go for word of mouth – but your requirements could differ from those of the recommender.

What you need is an objective measurement of quality, not the competing opinions of friends, coworkers and online reviewers.

Industry accreditations strive towards objectivity – and FENSA is an example of this. FENSA approval isn't just a rubber stamp. It tells you that you're in safe hands.

No FENSA approval, however, and you might as well work with a company whose motto is "Buyer Beware".

What other accreditations should you look for?

When shopping for doors or windows, you should look to see if the company's products are created under a quality-assured framework. If it's not obvious from the website or brochure, there's no harm in asking.

And if you're getting something installed, you need to be reassured that the installers know their onions. Again, there's no harm in asking nicely for accreditations – after all, this is your home and your money that are at stake. At the very least, an installer should have an NVQ in glass installation or surveying.

Conclusion

Choosing a door or window installer for your home isn't a decision that can be made lightly. You need to be as sure as you possibly can that the company you choose will do a good job.

So when you come to contact an installer, check to see if they're FENSA-approved. It's evidence that they're council-registered, that they follow all relevant building regulations and that their installations are energy-efficient.

DIY guide: replacing rotted wood around a window

Mon, 30 Sep 2024 15:53:35 GMT

Want to fix rotten wood on a window frame? Learn how to do a good job in 7 easy-to-follow steps.

Do you have a wooden window frame that's started to rot? You might be wondering whether to repair the frames or replace them altogether.

Deciding whether to repair or replace rests on the answer to a single question: will a repair job involve removing an entire piece of wood? If so, it's almost certainly time to replace the frame.

But if you're just looking at isolated spots of rot, you can absolutely repair the frame. As with all maintenance and installation jobs, you can get a professional in – but if you want to save money or simply enjoy the challenge, you can always do it yourself.

In this article, we walk you through an easy seven-step process that can make a rotted patch on a window frame look as good as new. We then look at when it's time to replace your rotted window frame and weigh up wooden frames against their modern uPVC equivalents.

What you need

Scraper
Drill
Two-pack filler
Wood hardener
Filling knife
Sandpaper
Paint
Paintbrush

Step one: preparing the wood

Take your scraper and dig out as much of the decayed, rotten wood as possible. If you can help it, leave the bottom bit of the frame intact. This is so you have a surface for the filler to sit up against.

Step two: drilling holes

Drill a hole or two in the gap you've created. This is so the hardener can penetrate the wood a little bit better.

Step three: apply wood hardener

Coat the surface with wood hardener. You'll want to do two coats to make it as hard as possible. Drying times vary but you'll probably be applying the first coat in the morning and the second coat at the end of the day.

Step four: bedtime

You need to let that second coat of hardener try overnight. Sweet dreams!

Step five: apply two-pack filler

Rise and shine! The previously rotted area should now be hard. You now need to apply two-pack filler. You'll probably need to fill the gap twice to make sure it's packed tight. Before you do the second fill, sand it down for a smooth texture.

Step six: more sanding

Once you've done your double application of two-pack filler, sand down the repaired area again. This is both to make it smooth and to shape it. You want the repaired area to blend seamlessly with the rest of the frame.

Step seven: paint the frame

Pick a colour of paint that matches the existing frame. Apply strips of painter's tape along the glass to avoid staining and then paint the frames.

Will it last forever?

No. If you repair a rotted window frame in this way, you're disguising the gap rather than fixing it for good.

This isn't necessarily a problem. Just be aware that you'll need to keep an eye on this area of the frame as it may rot again.

You should also be aware that wood rot weakens the structural stability of the frames, which can lead to security issues. Because of this, it can be advisable to replace the windows to ensure they're burglar-proof.

What causes wood rot?

There are two types of wood rot: wet and dry. Wet rot is caused by a type of fungus that grows in damp conditions and breaks wood down. Dry rot, by contrast, occurs in moist, poorly ventilated areas. The fungus sucks moisture from the wood, leaving it weaker than before.

Telltale signs of wood rot include:

A smell of mushrooms or fungi on the wood
Discolouration
A hollow sound when you hit the wood with a hammer
The wood being soft to the touch

If you're reading this article, chances are you're looking for a cure rather than preventative measures. But if you do want to prevent wood rot from happening at all, make sure your home is unaffected by leaks or damp. You should also regularly wipe down wood to avoid a build-up of moisture.

When should I replace a rotted wooden window?

The above method can be used on small areas of rotted wood. If this can't be done without removing entire pieces of wood, it's time to replace your frames.

If you do replace your wooden window frames, consider uPVC as a material. For our money, this tends to be the best choice in most circumstances.

What are the advantages of uPVC window frames?

uPVC window frames are preferable to wooden frames in several respects. First, they're highly durable, able to keep their shape and strength for 20 years or more. Compared to wood, it's super-hardwearing and not vulnerable to rot.

uPVC is waterproof, meaning your window frames won't contribute to damp, leaks or condensation. It won't warp in the heat, so it shouldn't become difficult to open and shut.

It's a doddle to maintain: simply wipe it down with an all-surface cleaner and a microfibre cloth to keep it clean. It won't rot or rust, and because it comes in a range of colours, there's no paint to flake or chip.

It's much more energy efficient than wood. It stops damp and cold from coming in and heat from leaking out. This has two positive effects. First, it can lower your energy bills as you won't have to use the central heating so much. Secondly, it reduces your carbon footprint.

On top of all this, uPVC provides superior soundproofing to wood – a godsend if you're troubled by loud traffic or noisy neighbours.

Finally, uPVC is extremely resilient and hard to break into. Windows with uPVC frames tend to be anti-crowbar, meaning they can't be jimmied open.

So, if your wooden windows are getting too rotten to repair, consider getting some uPVC frames installed. You won't look back!

3 composite door styles that will revitalise your home

Mon, 30 Sep 2024 15:25:55 GMT

Composite doors come in a range of attractive styles. Discover 3 collections that could transform your home.

The idea of "kerb appeal" is often mentioned in the context of buying and selling homes. A buyer's first impressions, they say, are crucial to securing a sale. If the facade is a mess, you'll need Versailles levels of beauty in the interior to change a potential buyer's mind.

But it's not just about selling your home. It's also about living in it. Having a good front door may not seem like a priority in life. However, it can change how you think about your home for better or worse – not least because you probably open and shut it a thousand times or more in a year.

The same goes for back doors and interior doors. Wherever it's installed, a smooth-opening, smooth-looking door is an asset to any home.

If you've got a classic wooden door, you may find it's getting a little worse for wear. Could it be time to give it a fresh coat of paint – or replace it entirely?

If you're leaning towards the latter, you should explore the world of composite doors . These have the appearance and functionality of a traditional door but are full of modern features to make them tougher, denser and more long-lasting.

On top of that, they come in a range of styles, from classic to contemporary. This means you can get a door that blends with your home's overall aesthetic.

Calder Windows' Definitive Collection contains several styles of composite doors that can revitalise your home. In this article, we look at three of the best.

The Traditional Collection

Sometimes, you want a classic look. Perhaps you're the understated type and want a door that doesn't make a fuss but looks pretty good on closer inspection. Or perhaps you want some old-school elegance, evoking times gone by.

If this sounds like you, our Traditional Collection is the place to start. It features a variety of easily recognisable, much-loved designs in a range of colours and textures. Oh, and like all our composite doors, you're spoiled for choice when it comes to knockers, letterboxes, house numbers and other furniture.

As for the glass itself, it comes in five levels of privacy, from one (least obscure) to five (most obscure) – so whatever level of privacy you require, we've got you covered. On top of this, the glass can be patterned or etched to your taste.

So, if you're looking to revitalise your house, not reinvent the wheel, check out the timeless designs in our Traditional Collection.

Contemporary Collection

Traditional door designs tend to go for symmetry and simple shapes. Contemporary designs lean towards the funkier side. If you're the kind of person who thinks bold is beautiful, you might find what you're looking for in our Contemporary Collection.

Of course, it's not all big and bold. It also features tasteful designs that are just that little less traditional looking – a long window strip down the centre, say, or an upper window in the shape of a diamond.

As with the Traditional Collection, the glass can be as austere or as decorative as you like and you can explore a plethora of furniture options. The result is a collection that's versatile enough to complement your home and your personality.

The Solid Collection

Don't want a window on the door? The Solid Collection is for you. It combines the best of the Traditional and Contemporary Collections without glass, drawing the eye to the door's colour and furniture.

The Solid Collection isn't tied to one aesthetic and can suit any property from a Victorian-style home to a new build.

What is a composite door, exactly?

A composite door is a door that combines a classic appearance with modern advancements that make it more durable, more secure and more energy efficient.

It will typically have a solid timber core surrounded by other materials including uPVC, laminate or GRP (fibreglass). This makes the door far sturdier than its traditional counterparts.

Why get a composite door?

When compared to wooden doors, composite doors are significantly more weather-resistant, more durable, more energy-efficient and more secure.

No rot, no rust, no warping, no swelling. Composite doors are built to withstand British weather and keep their fresh look for longer.

As well as saving you money (no replacement needed any time soon!) this means that composite doors are exceptionally easy to maintain.

They're designed to be energy-efficient – a quality that's good for your bank balance and for the planet.

And finally, they're highly secure, being both thicker and denser than standard doors. Ours come with multi-point locking as standard, so you needn't worry about break-ins.

All in all, composite doors are a great choice if you want a door that's built to last, built to keep intruders out and built to keep the warmth in.

About our composite doors

At Calder Windows, we stock a range of composite door styles. Truly, there's something for everyone.

This is partly a case of style, with traditional, contemporary and solid models all coming in a range of attractive colours and finishes.

But we know that doors are about more than just eye candy. They're fitted with super-secure advanced locking and made from high-end materials – two qualities which help make your home safe as well as attractive.

The quality of the materials also means that your composite door will look like new for years to come.

Finally, we're FENSA-approved – so you can be sure that the door is installed in line with up-to-date building regulations and energy-efficiency standards.

So, if you want to revitalise your home, take a look at our composite door collections . It's an investment you won't regret.

A guide to conservatory flooring

Tue, 10 Sep 2024 12:05:37 GMT

When you get a conservatory, you've got a choice of materials for flooring. Find out more in our article.

A good-quality conservatory can be a great addition to any home, whether you're looking for an extra room, a place to potter with your plants, a playroom for the kids or a relaxing space for reading.

Before you press the big button marked "buy", however, there's a lot to consider. You need to choose a style, of course. You might want to invest in some special furniture. And you'll need to decide on a material for the floor.

Carpet, laminate and wooden floors are popular choices – but your options don't end there. There's a whole host of possibilities, each with its own advantages and disadvantages.

At this point, you might feel like you're being asked to choose between 15 varieties of green apples – subtly different, for sure, but is there really much between them?

Well, leaving aside the all-important question of aesthetics, the easiest way to choose between them is to ask yourself what your conservatory will be primarily used for.

Is there going to be a lot of movement in and out of the extension? Then you'll want a material that's easy to clean. Will it form part of the kitchen? Then you need something that won't stain easily. Is it a space for the kids to play in? Then you want something durable and hard to skid on.

Answer these questions, and you should be able to pick the right material for your conservatory floor. Let's now take a look at those options in more detail.

Carpet

Carpet can be an affordable, versatile option if you want a conservatory on the cosy side. A good-quality underlay will keep the warmth in and improve the overall comfort.

If you've got a keen eye for aesthetics, carpet can pair well with furniture, decorations and the conservatory itself.

The big drawback, however, is that carpet is hard to clean when it's dirty. If your conservatory is likely to be regularly trodden on with muddy boots and shoes, you should look for another material.

Ceramic floor tiles

As well as being attractive, ceramic floor tiles are highly durable and easy to maintain. They resist water well, making them a good choice for kitchens with conservatory extensions.

Porcelain tiles can give your floor the look of natural stone at a cheaper price point – and unlike many types of stone, they won't need sealing or polishing.

Perhaps the key consideration, however, is how warm your conservatory is likely to be. If it gets chilly in winter, ceramic tiles won't help – not unless you also get underfloor heating, which will bring the overall price up.

Cork

Cork is tough, water-resistant, springy and warm underfoot. These qualities make it ideal for a kid's play area. It's also good at retaining warmth and minimising sound, both of which can enhance the cosiness of your conservatory.

And it's not just that it's easy to clean off any human footprints – it's good for your carbon footprint, too. Cork is 100% natural, renewable and recyclable. This is partly because cork can be harvested without killing the tree.

Laminate

Good-quality laminate can look just like traditional wood. However, it's far easier to install – and far cheaper too.

It's versatile, with plenty of tile, wood and stone patterns and finishes available. But unlike the original materials, it's extremely easy to hoover and wipe clean. This makes it a good option if you're in and out of the conservatory a lot.

One disadvantage is that it can be slippery when wet, making it less than ideal for households with young children. The finish can also fade – something to bear in mind if your conservatory gets a lot of sun exposure.

Stone

Stone flooring is a world unto itself, encompassing classic options like granite, limestone, slate and marble. Your choice will largely depend on the look you're going for – but you should also take into account that some types of stone flooring will need sealing, which can add to installation costs.

Another consideration is that marble is easily stained and marked – not great if there are kids at play or a kitchen counter nearby. It will also need to be polished regularly to keep its shine.

Vinyl

Vinyl is an ever more popular choice for conservatory flooring – not least because it can look like stone, wood or tiles at a fraction of the cost. It's also extremely easy to clean and maintain.

It's great for high-traffic areas, although it can be slippery when wet. Another downside is that it can scratch, stain and discolour easily.

If you're after affordable, easy-clean flooring, then vinyl could be just the thing. Be aware, however, that it doesn't have the durability of the other materials we've mentioned.

Wood

Wood is a classic look for a conservatory – especially if you intend to host dinners or other social occasions there. Take good care of a wooden floor and it can be a talking point for years to come.

Before going for wood, however, you should make sure your conservatory temperature is regulated. If it's very hot in summer and very cold in winter, the wood could warp. You can solve this with underfloor heating – but this will only add to the bill.

A compromise is hybrid hardwood flooring. This has the strength and durability of wood but is much easier to maintain.

How else can you make your conservatory warm?

Your choice of flooring material can make a noticeable difference to the warmth of your conservatory. But it's not just the floor that matters – the roof does, too.

As with floors, there's a range of options available. But at Calder Windows, we swear by SupaLite. This is a kind of tiled conservatory roof that's insulated to keep the temperature at an even keel in spring, summer, autumn and winter.

Conservatory pitfalls: how to get your summer room right first time

Fri, 30 Aug 2024 07:57:28 GMT

Getting a conservatory installed in your garden? Learn about 8 common pitfalls – and how to avoid them.

Thinking about getting a conservatory? Good choice. Not only can a sunroom be a great spot to unwind, potter with your plants, entertain guests or get some work done, but it can also increase the market value of your home.

But despite these perks – both economic and personal – there's no avoiding the fact that conservatories are significant investments. Not only that, but the installation process will mean giving up part of your garden for at least a couple of weeks.

Given the outlay and disruption required to get the conservatory of your dreams, you want to be sure that is , in fact, the conservatory of your dreams. Yet, too often, people part with their money in exchange for a bodge job that creates problems down the line.

Don't be that person. Keep these common conservatory pitfalls in mind to maximise your chances of a smooth installation and a much-loved addition to your home and garden.

1. Does it fit in?

Live in a new-build? Chances are you don't want a Victorian-style conservatory. Live in an Edwardian terraced house? You'll want something that matches the brickwork, the guttering – in a word, the vibe.

Customers sometimes put money before design and end up with a conservatory that sticks out like a sore thumb. Make sure you choose a design that blends with the look and feel of your home.

2. Is it the right temperature?

Too cold in winter, too hot in summer… How often we hear this from people who've installed a conservatory on the cheap, in a rush, or both.

It's such a shame – after all, one of the best things about a conservatory is that it can be enjoyed all year round. Why spend money on a room that's only usable in the spring and autumn?

The temperature of your conservatory will be affected by several factors. These include:

The number of windows and vents
Whether you get blinds installed
The insulating properties of the roof
What kind of glass you use

At Calder, we offer specialised warm roof conservatories . It's all down to SupaLite: a type of tiled roof that's specially insulated to ensure a comfortable temperature all year round.

3. Is it allowed?

Ah, planning regulations: a subject of confusion, irritation and suspicion for many homeowners.

There are two dangers here. One, you assume that planning regulations don't apply and push on with an illegal installation. Two, you get flustered about the complexities of the process and end up not bothering.

Neither of these scenarios is ideal. In both cases, you could end up having to take down your beloved sunroom.

Planning regulations aren't rocket science but they're not primary school science, either. Put aside time to check regulations long before spades go in the ground. Alternatively, choose a conservatory company that knows its regulatory onions.

4. Will the roof be quiet?

No one likes a noisy roof – especially in a room designed for relaxation. Yet many people end up with a roof that, when rained on, is far from relaxing.

Your main concern here should be the material you use for the roof. Polycarbonate roofs are cheaper than glass or a tiled roof like SupaLite . However, they can be extremely noisy in bad weather. On top of that, they're less thermally efficient than glass and they block out more light.

So, if you want a roof that maintains a good temperature and muffles outdoor sounds, try SupaLite .

But if you do have to go for polycarbonate, make sure it's good quality. Go cheap and you could end up with a leaking roof.

5. Will it have a good view?

Sure, you want your conservatory to look good from the outside. But what about the views from the inside?

We're not the first to point out that a conservatory can bring the outdoors in, acting as a bridge between house and garden. It only feels like this, however, if your conservatory is positioned to maximise the view.

6. Is it condensation-proof?

Issues with temperature control won't only affect your desire to spend time in your conservatory. They can also cause condensation – a sadly common problem with domestic sunrooms.

If you are afflicted by condensation, you can, of course, set up a dehumidifier. But prevention is better than cure, so make sure you're working with high-quality materials.

7. Will it be too bright?

So, you've planned your conservatory to sit at a point in the garden that has the best of all possible views. You cut the ribbon on the finished extension, pop in for a cup of tea and immediately find yourself squinting.

If your conservatory is placed in an exposed area, you should consider getting anti-glare glass, blinds, or both. Otherwise, you'll be reaching for the eye mask and wishing you'd done your research.

8. Will it be the right size?

This is the big one. People go small because it's cheaper, quicker to build and less likely to require planning permission. They then find themselves pouring tea in a glass-walled Wendy house.

The same issue can arise when people forget to factor furniture into their plans. Whether you're keeping things minimal with a couple of chairs and a table or splashing out on a dining table and chairs, you need to be sure that they'll fit comfortably in the finished sunroom.

How an installer can help

Thinking of building your own conservatory? If you're a DIY don who loves a challenge, crack on. But if your main consideration is saving money, we'd advise you to think again.

Nine times out of 10, DIY conservatory installers are laying booby traps for themselves – booby traps that will cost money to defuse down the line.

A professional installer, by contrast, will make sure you avoid these common pitfalls and ensure your conservatory is a place you want to spend time in.

The anatomy of modern windows: what's changed in recent times?

Fri, 30 Aug 2024 07:57:21 GMT

How are today's windows different from the 1970s? Get the facts from our window installation experts.

Take a time machine back to the 1970s and you'll notice a lot of changes. Glam rock hairdos. Pineapple on sticks as a given . Bell bottoms from here to ya-ya.

But things haven't only moved on in the fashion and food departments. Interior design, too, has changed subtly but undeniably. Put on an episode of Coronation Street from the 1970s and you'll see what we mean.

Windows in the 1970s didn't look dramatically different from today. But there was one big difference. You couldn't see it, but by golly, you could feel it. These windows let the heat out and the cold in like there was no tomorrow.

Yes, in the Energy Efficiency Awards, 1970s windows would go home empty-handed. They'd probably get booted out of the ceremony before the names were read. They weren't just bad: they were terrible. It was like the whole country was sitting in a draught.

But that's not the only difference. The glass industry has made several advancements in the half-century since the 1970s. In this article, we look at the most significant differences – and why they're better for your homes.

1. Materials

Back in the 1970s, window frames were primarily made out of aluminium. Today, you can still get them – but manufacturers and installers tend to work with uPVC frames.

This is chiefly because uPVC windows are more energy efficient than their aluminium forebears – though modern aluminium windows aren't too shabby in the efficiency stakes, either.

The paint used on windows has changed too. Lead-based paint has given way to calcium-based paint, meaning your window frames look brighter for longer.

Finally, the glass itself is different. Today's windows can be laminated, meaning that two or more sheets of glass are bonded together. As well as being harder to break, laminated glass helps keep out unwanted UV rays.

2. Glazing

The 1970s was the age of single glazing. This was problematic in a couple of ways. One was that it was terrible at keeping hot air in and cold air out.

There was some double glazing on the scene back then. But today, it's not an option – it's mandatory. Building Regulations Approved Document L (Fuel Conservation) insists that all new windows and doors in homes need to be double-glazed with low-E glass.

This isn't just about comfort (although it does make a huge difference!) It's also about reducing carbon emissions – and, along the way, saving renters and homeowners money on their energy bills.

Any double glazing installed between 1970 and the 2000s is counted as "old". Even millennial glass doesn't meet today's energy ratings.

This is partly because of the thermal break in the glass. This is the gap between the two panes that acts as an insulator. The bigger the gap, the more efficient it is. A new piece of double glazing will have a gap of around 16 millimetres compared to six millimetres back in the 2000s.

Triple glazing is also on the market. This is ideal for cold climates and can be a wise investment anywhere in the world if you want to reduce emissions, noise pollution and the risk of break-ins.

3. Security

Double glazing isn't just more thermally efficient than single glazing. It's also much harder to break. In fact, modern windows are far more geared towards safety than their 1970s equivalents.

Back then, you had to buy a lock and fit it on your window. Today, most windows have multi-point locking as standard. If you're shopping for windows and they don't have an integrated locking system, you should take your custom elsewhere.

Both of these things add up to peace of mind. You can't eliminate the possibility of a break-in. But in this regard, today's windows are a huge improvement on their predecessors.

4. Noise reduction

That thermal break between the two panes of glass in a double-glazed unit isn't just good for thermal efficiency. It's also good for keeping out unwanted noise.

If you lived on a busy street in the 1970s, your windows were about as much use as rice paper. Today's units, however, are pretty good at muffling sound.

And if you are dealing with an unusual amount of noise – living under a flight path, say, or next to an aspiring drum and bass DJ – you can invest in triple glazing or specialised acoustic glass. As well as protecting your ears and your sanity, these will add value to your home.

5. Ventilation

In the 1970s, ventilation was provided by leaning a window open. It was either open or it was shut. This isn't necessarily a problem you can discern. However, it contributes to poor air quality and condensation, which in turn can lead to health issues.

Today, building regulations say that you have to have a trickle vent – a slit in the upper frame of a window or door that provides a small but constant level of ventilation. These can be fixed or adjustable. The latter type allows you to control the airflow coming into the room.

Take away the world's trickle vents and you might not notice the difference. Nevertheless, they're good for air quality and help reduce nasty condensation.

Do you have old windows?

Is your home fitted with old windows? It might be time for an upgrade.

By "old" we mean any time between the 1970s and the 2000s (sorry, Gen Z). These windows might seem fine – but you can do better. A set of new windows will give your home a more up-to-date look and, most importantly, make it more energy efficient.

And you've got options. Perhaps you'd like timber effect uPVC windows, or aluminium frames, or a composite door. These come in a wide range of colours and finishes that can be tailored to your home's requirements. Trust us, you won't look back!

How often should you replace windows and doors?

Fri, 23 Aug 2024 06:05:35 GMT

Having problems with windows and doors? Find out whether it's time to get them repaired or replaced.

Having a problem with a window or door in your home? It could be that they're letting a draught in, they're a pain to open or they've just seen better days. In this situation, you face a choice: will you get them repaired or replace them altogether?

Without guidance, it's not an easy choice to make. Both require an investment of time and money. But it's a choice worth getting right.

Well-fitted, well-maintained doors and windows aren't just important because they improve the comfort and convenience of your home. They also affect your energy efficiency, which in turn can affect your energy bills, as well as your home's carbon footprint and market value.

As with many things, it's best to repair rather than replace if possible. But sometimes, you don't have that choice.

Here, then, are eight telltale signs that you need to get your windows and doors repaired or replaced.

When to repair or replace windows and doors

1. They keep getting stuck

Life's too short to struggle with doors and windows. If WD40 doesn't do the job, it's time to get the professionals in.

2. Your energy bills are too high

If your windows and doors are energy-efficient, they'll keep the cold out in winter and the heat out in summer. Old window frames and door frames start to leak, meaning you'll pay extra on heating and cooling.

Of course, before you commit to a repair or replacement, you need to be sure that your windows are the cause of your high energy bills.

3. You feel a draught

If you feel a draught – sometimes accompanied by a whistling sound – it's time to take action.

Draughty windows and doors can be caulked or weather-stripped. If these methods fail, it's time to get them replaced.

4. The glass gets fogged up

Double- and triple-glazed windows have an air pocket between the panes. If a seal breaks, condensation can get trapped in this gap.

Without looking at the window or door in question, it's difficult to say whether it's best to repair the seal or replace the whole unit. Your best bet is to ask a specialist.

5. The wood is rotting

Got wooden frames? There's one big reason why wood isn't used much for frames anymore: it rots.

But, of course, it doesn't rot all at once. First, it gets soft and spongy. If you poke a wooden frame and it feels like this, consider getting it replaced – preferably with a more durable material.

6. You're suffering from noise pollution

If you've got single-glazed windows, you'll probably experience a lot of noise from outside, be it from traffic or neighbours.

Luckily, modern glass is much better at soundproofing. You can get double- or triple-glazed glass to reduce noise pollution or invest in some special acoustic glass if you're in an especially noisy area (or if it's you who's making a lot of noise!)

7. You want to give your house a facelift

If your doors and windows are showing wear and tear, you can easily get them repaired. And if you don't like the look of them altogether, a new set can give your home a facelift.

8. You want to increase your home's value

Did you know that replacing your doors and windows can boost the value of your home? It's not just a question of kerb appeal. Many buyers will pass on a property that needs substantial DIY work – so do it for them and make the costs back in the value added to your home.

Should I repair or replace my windows and doors?

This is the million-dollar question. For our money, you should get your windows and doors repaired if the glass is broken, if there's a single component that needs replacing or if the frames are made from expensive materials. In these situations, a repair job will give you the result you need at a cheaper cost than a replacement.

However, you should consider replacing them if:

Your windows are getting towards the end of their lifespan (after about 15 years)
You're spending too much on energy bills and you can't find another explanation
You've got wooden frames that have started to rot
The windows and doors can't be opened and shut with ease anymore

How can I avoid replacing or repairing my windows?

Prevention, they say, is better than cure – and it's true in the case of your home's windows and doors.

The best way to avoid getting them replaced or repaired down the line is to get them installed properly to begin with.

However, we realise this isn't always possible. So, if you're lumbered with bad windows or doors, your best bet is to maintain them regularly.

This involves monthly inspections for leaks, draughts, cracks and holes. Check the finish. If it's a wood frame, is there any softness or sponginess? And so on.

On top of this, make sure you clean them regularly. As with all cleaning, little and often is better than a frantic deep clean once every leap year. Debris can cause windows and doors to stick – so you may as well clean them regularly and stop this from becoming a problem.

Final thoughts

Sometimes, a problem with a window or door can be fixed, whether it's a DIY job or done professionally. But at other times, you're going to need to get the whole shebang replaced.

When you do, it's essential that you get a reputable installer on board. Going cheap or going on trust can result in a bodge job – a recipe for more time and money spent down the line.

Instead, work with a professional, experienced installer. They can talk you through your options and give you a transparent quote based on your needs, not theirs. The result? Windows and doors that function perfectly, look great and add to the value of your home.

How to wallpaper around a window

Mon, 12 Aug 2024 06:23:27 GMT

Getting ready to put up wallpaper around a window frame? Follow our 7-step guide for best results.

"Either that wallpaper goes, or I do." So, they say, were the last words of the poet and playwright Oscar Wilde. An extreme reaction, for sure – but who among us hasn't looked at a wallpaper job and thought, "There's room for improvement"?

It's not just a case of designs and patterns, either. It's also that DIY wallpapering can result in some shonky results – especially if the wallpaper has been applied around a window.

Wallpapering around a window isn't easy. If you're not good with your hands, it can feel like an afternoon spent in one of the outer circles of Hades.

The challenge is twofold: one, getting the cuts right so they fit smoothly around the frame and, if there is one, inside the recess. Wallpaper has a habit of twisting out of shape. At times, you can feel like you're trying to straighten out a live serpent.

The second challenge is getting the pattern to match up.

Of course, there are patterns and there are patterns . Geometric shapes will be easier to match up than, say, a carnival of goat-men in a Bavarian forest.

The fact of the matter is that wallpapering around a window can be tricky if you've not done it before. If you get through our guide and still feel confident, get a professional in. But if you're up for learning a new skill with all the trial, error and tears that involves, here's how to do it.

Know your window

Before you reach for the wallpaper and scissors, you need to know your window.

The main reason for this is simple: the world is full of windows that are off-plumb (not exactly vertical) or not quite square. This can make it difficult to line up the different pieces of wallpaper.

It can also affect your choice of pattern. If the window is off-plumb, some patterns may not line up just right. Somewhat counterintuitively, you may want to go for a busy pattern as it can be easier to conceal a mismatch than with simple lines and geometric shapes.

Finally, you need to know if your window has a recess or not. If it does, the method will be slightly different.

What you need

Craft knife or large scissors
Wallpaper paste
Wallpaper brush
Spirit level or laser level
A pencil
Patience!

Step one: get the wall ready

If there are any gaps or imperfections in your walls, you'll need to fill them up with vinyl spackling paste or poly filler. You can also use sandpaper to smooth down any bumps.

Step two: find your starting point

Take a full roll of wallpaper and hold it horizontally from the right-hand side of the window. Place the mid-point on the edge of the frame and mark on the wall with a pencil where the wallpaper will sit.

Next, place the roll next to the pencil mark. Observe where each roll will drop at the corners. Use a spirit level or laser level to mark a level vertical line across the top of the window.

Then let the roll drop in front of the window on the right-hand side. Cut the wallpaper at the top and bottom of the recess. For this, you can use a pair of scissors or a craft knife. You should be left with a flap of paper that can be folded inwards. Fold this flap inwards and trim the wallpaper to meet the frame. Stick it in place with wallpaper paste.

Note: this last step only applies if you have a recess. If you don't, follow the steps above but cut off the excess rather than folding it inwards.

Step three: hang the second piece

Repeat step two on the left-hand side.

Step four: fill the gap

If you're using patterned wallpaper, this is where it can get tricky.

Imagine a shirt with a zig-zag pattern. Most people would want the patch pocket to match the lines of the shirt rather than clash with them. Some people like a bit of wonkiness. The same principle applies here.

There'll now be a gap between the first and second drops that needs filling in. Measure the gap between each side and cut out a piece of wallpaper. Paste it in between the two above the window, taking care to match the pattern. Trim any excess where the paper meets the window frame.

Remember that if your window is off-plumb or not quite square, you may have trouble matching them exactly. In this case, it can be advisable to use a busy pattern that will conceal the mismatch.

Step five: tackle the bottom

You now need to apply a piece of wallpaper from the bottom of the window down to the skirting board.

Step six: tidying up

Now your wallpaper is hung, smooth it out with the brush, dabbing in any bumps, ridges or other imperfections.

Step seven: step back and admire your handiwork

Congratulations! You've successfully wallpapered around a window. Time for a cup of tea…

Fun fact

Did you know that wallpaper was taxed between 1712 and 1836? Introduced by Queen Anne, the tax started at one penny per square yard, rising to one shilling in 1809. People got around the tax by buying plain paper and stencilling patterns by hand.

Conclusion

So there you have it – your seven-step guide to wallpapering around a window.

Perhaps the biggest challenge faced by DIY window wallpaperers is working with a wonky window (now there's a tongue-twister for you). If your window is off-plumb or not quite square, consider getting it replaced by a specialist. This will improve your chances of a neat job.

Whatever route you choose, we wish you the best of luck!

Home security 101: tips and safeguards you need to know

Wed, 31 Jul 2024 21:57:16 GMT

We all want to feel safe and secure at home. Learn 6 simple steps you can take to boost home security.

We all want a home that feels comfortable and secure. We want to feel safe at home and to safeguard our families and valuables.

After all, nobody wants a break-in. There's no worse feeling than knowing you've had an intruder in your house. After it happens, it can be hard to shake the feeling that you're at risk.

So, let's look at ways we can stop it happening in the first place. In this article, we'll recommend security best practices that you can put in place without breaking the bank.

But first, let's look at a few FAQs.

How common are burglaries?

You may be surprised at just how common burglaries are.

In 2023, there were just over 200,000 reported break-ins at residential properties in England and Wales. Throw in business addresses and the total tops 300,000. Yikes.

What is the cost of a burglary for a homeowner?

On average, each break-in causes around £1,500 of property damage. On top of that, our uninvited guests typically remove between £2,000 and £3,000 in stolen goods – and a hefty 84% of homeowners are left in emotional distress once the dust has settled.

As you can see, spending a little now to put the right security measures in place could save you a fortune further down the line.

Is it safer to leave lights on?

It's a myth that leaving a light on makes your house less likely to be targeted.

So, there's no need to bother with timer switches – they're a waste of time and electricity. In fact, they might even serve as a beacon that tells people you're away.

When do burglaries happen – and how?

Over half of residential burglaries happen under the cover of darkness. And burglars almost always gain access by forcing a door or window.

This kicks us off nicely with the first of our safety tips…

Tip 1: make sure your locks are solid

Deadbolts are the kings of locks. They're a must on all exterior doors.

Deadbolt locks are operated by a key or thumb turn and have no spring-loaded parts. This means they can't be opened through the crack between the door and frame.

Spring-latch locks are among the weakest locking systems. They can be opened from the exterior using a thin blade or credit card – just like in the movies.

If you have spring-latch locks on any exterior doors in your home, you should consider changing these to deadbolts as soon as possible.

Deadbolts come in a range of shapes and sizes. The more bolts that lock into the frame, the more secure the lock.

Tip 2: secure your windows

Now that your doors are locked firmly, it's time to look at your windows.

Often, the weakest part here is the glass itself. That's why double glazing is a must. Good-quality double-glazed windows can often withstand attack from objects like bricks. And thanks to the glazing design, it's almost impossible to remove a double-glazed window pane from outside.

UPVC windows can be locked with an espagnolette locking system. Specially designed for windows and UPVC doors, these locks have a multi-point bolt system, meaning that windows are secured at more than one point along the un-hinged edge.

These locks should always be used when windows are shut – and especially when your house is vacant.

Tip 3: change the locks when you move in

Professional locksmiths advise that you should change all exterior locks when you move into a new home.

This ensures you're the only key holder, so you'll be safe even if unsolicited copies of your keys are changing hands.

Remember: even the most secure locks in the world are no match for a stolen or copied key. If a criminal has the key to your home – and you haven't taken the time to change the locks – they could open your front door in a matter of seconds.

Tip 4: always have a backup

Why use one lock when two or more will do? After all, there's no such thing as "too secure", so it's worth installing backup locks to help deter those particularly persistent intruders.

Add-on locks come in all shapes and sizes for both doors and window frames. There's the classic security door chain, for instance, which lets you open the door an inch or two before deciding whether to grant entry. Then, at the premium end of the scale, there are Digi-locks that require a code, fob or even biometric data to get through.

Tip 5: install an alarm

A good, loud alarm system can be a burglar's biggest enemy. That's because potential thieves want to avoid any attention – especially when trying to gain access to a building.

Even a basic electric-current alarm system can be enough to put them off. These work by monitoring door and window entry points. An open door or window on an armed system will disrupt the electrical circuit and trigger the alarm.

More advanced systems work by transmitting signals by wire (or wirelessly) to a control panel, which can be monitored by a third party or linked up to a smartphone.

Remember: if you're installing a wired alarm system, request that the wires be placed out of sight or hidden in walls. A snipped wire can disable this type of system.

Tip 6: get a doorbell camera

Doorbell camera systems are becoming ever more popular and are convenient for a whole range of reasons. After all, we all hate missing parcel deliveries!

They also punch above their weight in terms of security, as they serve as cheap CCTV systems for your property. The technology can be linked to a smartphone and often integrates motion detection and infrared as standard.

Get these from as little as £40 and start making your home security feel a little smarter.

How we can help

So, what if all that stands between you and the outside world are some old sprung locks and a bed of spiky rose bushes?

Well, fear not. Here at Calder Windows, we offer a wide range of doors and windows that are built with exceptional security in mind.

Small conservatories: making the most of cramped or tricky spaces

Wed, 17 Jul 2024 08:00:03 GMT

Dreaming of a conservatory but unsure if it will fit on your property? Get the answers you need in our guide.

If you live in a property that has a small, cramped or awkwardly shaped garden, you might have resigned yourself to a life without a conservatory. Surely a conservatory in a small garden is like an AGA in a kitchenette?

In fact, tight spaces don't have to be a problem and small can be beautiful too. Done well, a small orangery or lean-to conservatory can be a great addition to gardens and courtyards of all shapes, sizes, styles and materials.

Not only that, but a small conservatory can also give you the benefits of a conservatory at a fraction of the cost and with a fraction of the upkeep needed.

Like a standard-sized conservatory, a small conservatory extends your living space, brings you closer to the outdoors and can even add market value to your home. The big difference is that a small conservatory is low on maintenance and low on repairs.

Plus, it's less likely that you'll need planning permission – although there are some exceptions to the rule and you should always check before contacting an installer.

What are the types of small conservatories?

If you have a small garden or other outdoor space, you can get small versions of most styles of conservatories. There's no reason why you shouldn't have a small Victorian-style conservatory in a tight space.

That said, many homeowners find that lean-to conservatories work best of all. This is because a lean-to sits against the wall of your house and takes up less overall space than other kinds of conservatories.

If a lean-to isn't for you, you might want to consider a small orangery or sunroom. These provide cosy spaces without taking up too much room.

Can you put a conservatory on a park home?

In theory, there's no reason why a park home owner shouldn't build a conservatory. Many do! However, you'll need to check with a few different people before contacting an installer.

First, you need to check with the park owner. The response you get will depend entirely on their specific rules and regulations.

Next, you should look into getting planning permission from the local council. If you want to be extra sure, check with the environmental health officer (EHO) too. It's rare but not unknown for permission to be granted by the local council, only for an EHO to reveal that the conservatory is a fire risk. If this happened to you, you would have to remove your extension.

A conservatory can be a great addition to a park home – but make sure you check with the appropriate authorities before the spades touch the ground.

What style of small conservatory should you go for?

As with any extension, the main consideration with a small conservatory is finding a style that complements your home. However, a small conservatory throws up a couple of issues that larger models don't.

First, you need to think about the material of the roof. To maximise the light coming in, you might want a glass or polycarbonate roof. However, if you have to tuck your conservatory under trees, you might want tiles to protect against falling leaves.

Then there's the question of size and shape. This will partly depend on the primary function of the conservatory.

If you're planning on using it for dinner parties, say, you'll need the maximum possible floor space to avoid being cramped. But a conservatory used mainly for potting plants or unwinding with a book will need less overall space.

Finally, there's the question of budget. This will be a key factor in deciding on your conservatory's materials and dimensions. But whatever your budget, you should be able to get the style that best suits your home.

Do you need planning permission for a small conservatory?

Local councils place limits on the size and placement of conservatories. In some cases, you may need to apply for planning permission. In the case of small conservatories, however, this is rarely the case.

Even so, it's best to check before you get to work as building without planning permission is a so-called "planning breach" and can be penalised with an unlimited fine.

Can a small conservatory go up to your boundary?

If your garden is on the small side, you may have to build your conservatory right up to the boundary. This should be fine, so long as it doesn't cover more than half of the area around the house.

However, if you're building it up to a boundary that sits under or near a wall or foundations, you should tell your neighbour and ask for approval. This is in line with the Party Wall etc. Act 1996 : a piece of legislation that's separate from planning and building regulations.

Boundaries are one of the biggest sources of tension and conflict between neighbours in the UK. So, make sure you keep your neighbours in the loop before calling in the installers.

Final thoughts

At Calder Windows, we've been installing conservatories for decades – so we know better than most how great an addition they can be to gardens of all shapes and sizes. They're a stylish and cosy way of making your home that little bit bigger and provide a great spot to work, unwind or a bit of both.

We also know the challenges that can arise when you're getting one built in a cramped or tricky space. Nine times out of 10, however, these challenges can be addressed.

At the end of the day, there's no reason why you can't fit a small conservatory in a tight space – you just have to be a bit creative about it. Dream big – and build small!

3 ways to decorate a window: helpful tips for all seasons

Fri, 12 Jul 2024 07:32:42 GMT

Bored of looking at plain windows? Learn how to enhance your home by adding a little glam to your glazing.

When you first read the heading, you probably pictured autumnal displays with pumpkins – or twinkly, snow-laden windows dressed up for Christmas. However, we've got something a little more useful in mind.

See, while it might sound a bit "out there" to talk about decorating your windows, most people do it without really realising it.

Whether it's curtains, drapes, Venetian blinds or blackout blinds, what we add to our windows makes a drastic difference to our homes. It affects the overall ambience and can be a real mood setter, depending on the environment.

Think curtains are just curtains? Think again. Let's look at three classic window dressings and explore how they can make your home a happier place to be, no matter the season.

1. Curtains

Ah, the age-old classic. While curtains have been considered a little passé in recent years, they've since made a huge comeback. In fact, curtains are now among the most popular window dressings for younger homeowners.

It's easy to see why. With a huge variety of styles, fabrics and colours on offer, curtains can help to complete a room like no other window dressing.

The trick with curtains is to lead with length. This sets the tone for the space.

A tailored curtain, for example, would sit around a quarter of an inch from the floor. A dramatic style, on the other hand, might pool at the floor for an elongated effect.

Now, if interior design isn't your forte, there's no harm in going for the ever-trusty casual approach. This simply involves matching the curtain length to the height of the window.

There's more to consider than length alone. You should also think about the type of fabric you'll use and its colour. Heavier and darker fabrics, for instance, can help to control the amount of light that enters the room.

Follow these tips and you'll ensure your room is inviting and homely, no matter the season. Whether they're closed for comfort or blowing in a soft summer breeze, curtains are always versatile and always effective.

2. Blinds

Thinking about installing blinds? There are a couple of points you should consider.

The first is the positioning of the blinds. Are they going to be fitted inside the window recess or outside of it?

Placing them inside is the more flexible option. It means you can install curtains alongside the blinds and can further decorate the space with ornaments or plants. You might choose to install them outside the recess, meanwhile, if your window frame is too narrow to accommodate the blinds or if you want to show off a decorative window.

Your choice also affects the amount of light that can enter a room. If the blind is hung inside the recess, it will prevent more light from entering the room, whereas a blind fixed outside the recess will allow more light to pass through.

The next thing to consider is the type of blind you'd like. Trust us – there are tonnes to choose from! Roller blinds, Venetian blinds, blackout blinds, Roman blinds, pleated blinds… The list goes on.

Make sure to familiarise yourself with the many options available. Choose correctly and your blinds will complement and enhance your décor, whether you're aiming for something minimalist and understated or going for full-on glamour.

3. Accessories

Now, we're not just talking about seasonal themes such as Christmas, Easter and autumn. We're talking all-year-round sprucing.

The accessories that you add to your window can help to solidify your décor and the overall style of the room.

If you're going for a modern organic look, try adding large oversized vases in neutral colours, along with stacked books and reed diffusers. This look would go beautifully with long, draping curtains and wooden blinds that let the light pour into your living space.

Dark and mysterious rooms can be accessorised with deep green plants, large candles and textured ornaments. If you like this look, go for dark, heavy fabric curtains that frame the window and keep the tone secretive yet inviting.

Whether you're styling with themed accessories or keeping it simple yet effective with a few ornaments, there are tonnes of options to choose from. Let your own preferences guide you and you'll soon have a window space that feels like a focal point for the whole room.

How to measure for new windows

Mon, 08 Jul 2024 17:13:54 GMT

Getting new windows and need to take measurements? Follow our guide to make sure you get them right.

So, you're looking to get your windows replaced? Whatever the reason, you're going to need a quote from the window installer. And to get that quote, you need measurements.

Yes, measurements: those numerals and decimals that can make or break a project.

Why? Because when it comes to windows, the devil is in the details.

Too big, and you're pumping your central heating into the street in winter and inviting the cold air in for a cuppa in winter. Too tight, and you're going to have a creaking, scraping, hard-to-handle window on your hands.

So, accurate measurements are important. "But surely", we hear some of you say, "accurate measurements are a case of simply getting out the tape measure and jotting down the width and length?"

Well, yes and no. You don't need elaborate technical equipment or specialist knowledge to measure your windows correctly. But you do need to follow the correct method to ensure your installer can give you the right materials.

In this blog post, we talk you through the method you need to follow as well as some common mistakes that people make. Then we weigh up the pros and cons of doing the job yourself versus getting a professional in.

The method

When it comes to measuring windows, accuracy is all. An incorrect window size is a waste of time and money, so make sure you measure and measure again.

And remember, when we say "measuring windows", we mean just that: the windows themselves. Don't measure the window plus the casing or moulding – just the window.

1. Measure the window's width

Take three measurements across the window from brick to brick. First, measure from the top, then the middle, then the bottom (along the sill).

Why? Because window openings are often uneven – especially in old houses. You need to take these possible discrepancies into account before contacting your installer.

Once you've got your three measurements, highlight the smallest. This is the one you're going to use.

2. Measure the height

Now, you want to repeat step one but go all the way down from the top of the window to the sill. Do this on the left side, the right side and down the middle. Again, go with the tightest measurement to minimise the chances of an incorrect fitting.

3. Measure the depth

Now you want to open the window and measure the depth of the sill. This will obviously be much smaller than the others – a matter of inches. Again, you need to take multiple measurements and pick the smallest.

Do you need toughened glass?

If the glass line is lower than 800 millimetres from the ground, your window will need to be made from toughened or tempered glass, which is a type of safety glass. This is a BS (British Standard) regulation and applies to both domestic and commercial settings.

Common mistakes

Follow the method above and you should be good to go – especially if you remember to measure and measure again.

However, there are a number of common mistakes that people make when measuring windows for replacement. Make sure you don't make them yourself!

1. Measuring the windows from the inside

Measure the window from inside your home and you might not get an accurate reading. This will cause problems down the line when you have to replace your replacement.

2. No expansion gap

Window frames can expand in the heat. That's why there needs to be an "expansion gap". The alternative is for the frame to expand and the window to become hard to open. A good window installer will take this into account, but it pays to be aware of this small but important detail.

3. The window isn't level or plumb

There's no guarantee that your current window has been installed properly. You should check to see if your window is square before submitting measurements to the installer.

You can do this by putting the tape measure in one corner of the window and measuring diagonally from there to the opposite bottom corner. Do this again with the other two corners.

If these two measurements aren't identical, the window isn't level. This will need to be communicated to your installer so you can be sure you'll get a good fit.

Should you replace windows yourself?

When it comes to home improvements, it's never been easier to do it yourself. Once upon a time, you'd need someone to talk you through your options. Nowadays, you can read a blog or watch a YouTube tutorial and hey presto, you're ready to get your tools and start work.

But there are two main reasons why people go DIY – and in our opinion, only one of them makes real sense. If you love DIY, don't let anybody hold you back. But if you're doing it yourself because you think it'll save you money, you might want to think again.

When you pay a professional to replace your windows, you're not just paying for manual labour – you're also paying for expertise. Of course, you can get this expertise yourself. But it's going to cost you time and money.

Secondly, doing a DIY job when your heart's not in it is likely to result in mistakes. And in the context of home improvements, mistakes are going to cost you. The best-case scenario is that you'll end up with a slightly wonky job. The worst-case scenario is that you end up paying for a professional to fix it for you at great expense.

So before you dive into a DIY window replacement project, ask yourself this: are the savings you could make worth the stress and the possibility of having to start again with a professional? If the answer is no, get in touch . We'll be more than happy to help you nail your home improvement goals.

How to cover windows for privacy

Mon, 24 Jun 2024 07:46:27 GMT

Fearful of prying eyes? Discover some of the most effective ways to cover your windows for added privacy.

Beautiful windows can be a focal point for the rooms in your home – but they bring so much more than pleasing aesthetics.

Not only does a well-ventilated space reduce the risk of condensation and mould developing in your home, but exposure to natural light also has well-documented positive effects on health and mood. A recent study even suggests that having more windows correlates with increased creativity.

But every silver lining has a cloud. For all their benefits, windows are… well, transparent. They can contribute to a feeling of well-being – but they also allow prying eyes to peek into your affairs.

So, how do you best cover your windows when you need a little more privacy? And is it possible to do so without losing all of the benefits from the windows in your home?

Let's find out.

What to consider before you start

With so many options for window coverings out there, taking note of a few factors may help in your decision-making.

1. What's your budget?

From cheap DIY decals to luxe shutters, the price range for window coverings can be vast. Be sure to decide roughly how much you're looking to spend to help narrow down the options.

2. How much privacy do you want?

Different areas in your home may need different levels of privacy. Consider permanent solutions for doors, bathrooms and street-facing windows.

3. What types of windows do you have?

Do you have oddly shaped or sized windows? Traditional coverings may not cut it

4. Do you want to keep the light?

Many options will block out daylight as well as passing eyes. Decide whether you'd like the privacy without compromising on light.

What about curtains and blinds?

For many years, curtains and blinds have been the go-to solution for window privacy. They're fairly affordable, quick to install and come in a huge range of styles and colours.

However, while they're still a great choice for some, you may be looking for something a little different.

Various factors can mean that curtains and blinds just aren't right for you. For starters, cords and ties can be hazardous for young children and pets. And while they offer complete privacy, you have to compromise on sunlight.

What's more, if you redecorate your room, you may be left searching for a matching replacement. Back to square one…

So, if you're looking for a different way to ensure privacy at home, consider these practical alternatives.

Quick fixes

1. Window furnishings

Are you looking for an easy way to make your rooms less visible from the street? Some cleverly placed bric-a-brac is a quick and customisable solution.

Whether it's family heirlooms or quirky secondhand treasures, your window displays can give the outside world a hint of your personal style and are easily swapped and changed when needed.

2. Privacy screens

Another option that's simple to install and remove is a privacy screen or room divider. Because it's portable and easy to store, it means you can choose unobscured views or complete privacy at the drop of a hat.

Dividers vary in price from preloved bargains to pricier statement pieces. They come in a wide variety of shapes and styles to suit your home's look and feel.

DIYers dreams

3. Planters and window boxes

For the more green-fingered among you, planters and window boxes can be a great way to add a little more privacy without completely blocking the view.

This option is great for tenants in rental properties, as well as homeowners, because the greenery can be removed with ease.

A colourful window box or pretty line of plants won't completely block the view. However, it does offer a fairly inexpensive and attractive solution for rooms that don't require so much privacy.

4. Decals, stickers and stencils

An easy DIY option that offers partial privacy, window stickers, decals or stencils can be purchased fairly inexpensively from many online suppliers.

These decorative pieces are a great way to personalise your windows and can be removed without much hassle. They don't offer the greatest level of privacy but work well if you just want to mask a little of the view from the street.

5. DIY films

DIY window films are a popular way to add a little more cosiness to a room. There are a huge number of styles available to buy – all provide extra privacy without blocking out all the light from your windows.

The films can be a little tricky to apply and don't last forever. However, they make for a nifty solution for those on a tight budget.

Long-term solutions

6. One-way film

Professionally fitted one-way window film is a clever way to stop any spying glances into your home.

Giving a mirrored effect from the outside, one-way film means you're still able to see out of your windows while passersby aren't able to see in. The film also dims but doesn't block light, so your rooms can still benefit from sunshine.

It's worth noting, however, that one-way film only works in the daytime. It won't offer any privacy at night.

7. Shutters

If you can afford to splurge a little, consider interior or exterior fitted shutters. These act as permanent and attractive privacy coverings for your windows.

While not the cheapest option, solid shutters offer complete privacy for your property and can help boost your home's kerb appeal.

Some shutter designs have the added benefit of a tilt rod. This allows a little light into your room in a similar fashion to a blind.

8. Frosted and decorative glass panes

A great all-rounder, professionally fitted frosted or decorative glass offers complete privacy without compromising on any natural light.

Available in a large range of patterns and designs, opaque glass panels are an attractive way to bring a bit of life into your windows while keeping your home private and secure.

This option is ideal for street-facing windows, exterior doors or anywhere you would like a little more seclusion – such as a bedroom or bathroom. Frosted and decorative panes are also ideal for oddly shaped frames as they are made to measure.

Choosing a reputable installer will ensure your windows stay private and rooms stay bright for as long as you need them to be.

Calder Windows has supplied and fitted top-quality windows and doors in Yorkshire for more than 30 years.

We have a huge range of windows available in a variety of professional finishes – including frosted and decorative glass options.

Conservatory too hot in summer? Try these 8 clever fixes

Mon, 17 Jun 2024 15:29:40 GMT

Is your conservatory getting too hot in warm weather? Keep things nice and cool with these 8 tips.

Have you ever slid open your conservatory doors only to be hit by an uninviting wall of heat?

It happens. Although they're designed for maximum enjoyment of the summer sunshine, some conservatories just get too hot to enjoy in warm weather.

The good news is that it doesn't have to be this way. Here are eight clever fixes you can try to keep your conservatory cool and welcoming no matter how hot it gets.

1. Get some blinds

One of the easiest ways to keep your conservatory cool in the summer is to fit some blinds. They shield your room from sunlight and its heat while adding a stylish touch to the space. Plus, if someone wants the sun and someone else wants the shade, they can each customise their nearby blind configurations without affecting the other.

Bonus: drawing the blinds can also help keep the heat inside during colder months. Add a heater and some blankets and you'll have yourself a cosy spot all winter round.

Some popular blind variations for conservatories include:

Pleated blinds: made with lightweight fabrics and folded in an accordion-like shape
Venetian blinds: perhaps the most common type of blind, Venetian blinds feature horizontal slats made of plastic, wood or aluminium that can be rotated in unison
Roman blinds: fabric-based pleated blinds that fold underneath themselves when raised
Roller blinds: these are just like Roman blinds except they roll up rather than concertina up

2. Install air conditioning

Another way to keep your conservatory nice and cool in warmer weather is to install an air conditioning system.

Your typical air conditioning unit doesn't come cheap. However, it's a highly effective option if you have the spare cash to spend. It works by circulating cool air in your conservatory.

The ideal model for most conservatories is a small air conditioning unit. It should fit discretely into your space at floor or ceiling level. Alternatively, you can mount it onto a wall.

Are you likely to have small children using your conservatory? Air conditioning is usually considered a safer option compared to electric fans, which can trap and nick tiny fingers.

These units usually have a heating function too, so you can use them to warm up the space in colder months.

3. Let the air move

Keeping the air moving with effective ventilation is key when it comes to keeping conservatories cool.

Here's an easy solution: keep a door open to let hot air flow out and a cool breeze flow in. If that's not feasible for you, try installing small outward-opening ventilation areas at the top of each large windowpane that allow hot air to flow outside.

You can also use an electric fan to circulate the air. Keep your windows closed and position the fan towards where you're sitting. Or consider a roof fan if you have little ones around who could be harmed by a stand-alone or countertop fan.

4. Glass roof? It's time to adapt

If you need a roof upgrade or want to totally refurbish your conservatory, you should consider a thermal roof this time around rather than a glass roof. Thermal conservatory roofs help regulate the temperature inside.

Really want to see the sky? Go for shaded, reflective glass instead – or an insulated roof with a large roof light .

If you already have glass roof panels in your conservatory and can't afford a roof upgrade right now, you can try adding an opaque or translucent film. When fitted to glass panels, this prevents some of the sun's heat from getting inside.

5. Take any rugs up

Got a lovely wool rug adorning your conservatory floor? We've got some bad news for you: it could be contributing to the heat in warmer weather.

Natural fibres are designed to trap heat – that's why our cosiest winter jumpers are made from wool. It's best to roll up those fluffy rugs and store them for the colder months if your conservatory is getting too hot.

6. Opt for light furniture

You know how wearing black in hot weather makes you sweat buckets? That's because light is attracted to dark colours – and the same principle applies to any dark furniture and furnishings in your conservatory.

Make sure you choose soft fabrics (avoid leather) in light colours. And when it comes to paint and wallpaper, go for white or pastel colours.

7. Plant some trees in your north-facing garden

Deciduous trees like beech, birch, ash and whitebeam can be strategically planted outside your conservatory to create shade and help protect you from the heat of the summer sun. Try planting some if you have room.

8. South-facing garden? Try a retractable canopy

If you don't have any trusty tree pals to help keep you cool in the summer, you can always try fitting a retractable canopy to the side of your conservatory.

These devices can help regulate the temperature inside your conservatory by shielding it from the heat during the sunniest parts of the day.

You can even leave the windows open to let in a breeze while enjoying protection from the sun.

Want to keep your conservatory at the perfect temperature all year round? Calder Windows is a registered installer of SupaLite's insulated conservatory roofing .

This revolutionary tiled roof system doesn't just regulate heat – with its attractive and robust design, it transforms conservatories into practical modern living spaces.

When did we start using doors?

Mon, 10 Jun 2024 10:00:45 GMT

Wondering when we first start using doors? Get the answer and learn some fascinating door history facts.

In a doorless world, there had to be one human brave enough to dream. To dream of a world where they could shut strangers out of their personal space in one swift movement. Slam!

But when did that become a desirable idea? When did we start using doors? And were the first doors different to the doors we use today?

Keep reading to find out.

Did cavemen have doors?

Cavemen and cavewomen didn't use doors, but they did use door frames in the latter part of the Stone Age. Or, at least, they look a bit like door frames to our modern eyes.

Yes. When our ancestors gave up their nomadic lifestyle, they started building frames using materials like stones, wood and animal skins.

And who knows? Perhaps they chose the prettiest skins and shiniest stones to give it a touch of decorative appeal while they were at it.

The first door

History's first recorded doors can be seen in 4,000-year-old Egyptian tomb paintings. These so-called "false doors" appear to have single wooden panes. Some were drawn with one opening, while others resemble double doors.

In case it wasn't clear, false doors are not doors. They're pieces of decorative wall art that are meant to look like doors but not act like doors. A trick of the eye – similar to the trompe-l' œil paintings of the Baroque era.

Since they often appear in tombs, it's thought that false doors represented gates to the afterlife for the deceased.

So, we don't know who invented the door. But if the ancient Egyptians were painting false doors, they must have been using real doors.

Otherwise, it would be like inventing Quorn before realising that meat was a thing. Not likely.

The second door?

Around 13 years ago, archaeologists in Zurich unearthed one of the oldest doors ever found in Europe, dating it at 5,000 years old. This was around the time construction began at Stonehenge.

The door was made of poplar wood and was in good condition with well-preserved hinges.

At the time, the weather would have been harsh, with cold winds blowing across Lake Zurich. Doors like this would have helped keep out the chill.

More famous old doors

By biblical times, doors were firmly established in the Middle East. King Solomon's temple, which existed from about 900 BC to 500 BC, is described as having an olive wood door that's carved and overlaid with gold.

More evidence comes from the archetypal Greek poet, Homer. Writing in the late eighth or early seventh century BC, he mentions doors cased in brass or silver.

The Greeks and Romans got innovative with their designs, experimenting with triple doors, folding doors and sliding doors, as well as using your standard single and double doors.

In the church of Santi Cosma e Damiano in Rome, there are some bronze doors with a design of two leaves, each with two panels. The doors are framed in bronze, highlighting the exceptional metalwork that the Romans are known for.

Ancient automatic doors

Heron of Alexandria, a Greek scholar of the first century AD, was the proud inventor of the first known automatic door.

Several more ancient boffins came up with similar ideas. During the reign of Emperor Yang of Sui, an unknown craftsman made an automatic door for the royal library. And an Arab inventor named al-Jazari illustrated automatic gates powered by water.

Heavy metal doors

The 11th and 12th centuries saw an explosion in the use of bronze in door manufacturing.

One notable building to feature bronze doors is the Battistero di San Giovanni in Florence. Another is the Church of the Nativity in Bethlehem, whose doors are decorated with cut-out bronze patterns.

Examples abound outside of the Christian world, too. Mosques in Cairo commonly used highly decorative sheets of iron or bronze for their doors. And when they didn't, they tended to use wood-framed doors with interlaced diamond and square designs. \

Renaissance doors

Doors were transformed into works of art during the Renaissance period. Artists like Da Vinci and Michelangelo were honing their skills and the world was falling in love with beauty again.

Cathedrals embraced classical Greek designs and allowed their places of worship to be decorated – including the doors.

In Spain, Tuscan-style doors were the hot new trend. A sight to behold, these doors were decorated with hundreds of handmade iron nails or clavos . They also often featured carved rectangular panels framed by borders full of birds, figures and foliage.

France, meanwhile, put religion first and created some of the most beautiful cathedral doors ever known. These doors often sported Gothic details, as well as coats of arms and royal motifs. They were usually made out of cedarwood – and the grandest of them featured high canopies.

Soon after this, French doors began to be decorated with figures, landscapes and fine borders.

England's oldest door

Dating back to 1050, the oldest door in England is at Westminster Abbey.

In 17th century England, it was common for doors to be raised with bolection mouldings – and people were not shy about displaying intricate carvings on their doors. In the 18th century, meanwhile, it was fashionable to have egg-and-dart decorations on your doors.

The world's biggest doors

The largest doors in the world can be found in NASA's Vehicle Assembly Building (VAB) at the Kennedy Space Centre. There are four of them in total, each a humongous 139 metres (456 feet) tall.

Why are they so tall? Well, the VAB was originally built to assemble Saturn vehicles for the Apollo missions. If you're building a rocket, you need a pretty big door.

How long do conservatories last?

Mon, 03 Jun 2024 09:29:38 GMT

A good conservatory should last for years. Find out the factors that affect this in our handy explainer article.

A conservatory can be a fantastic investment. It can give you extra room to play, relax or work in. It can bring home and garden closer together. It can even add value to your property.

But there's no two ways about it. A conservatory is a big investment – and unlike other investments, you can't try before you buy. Once it's erected on your property, you can of course make modifications. But you can't take it back and get a replacement.

This is why the question of durability is so important. If you're going to invest in a conservatory, you need to be sure that it's going to last.

In this article, we explore the question of how long a conservatory will last – and what you as a consumer can do to lengthen its life span.

Conservatories and the Good Rule

In the world of music recording, there's a concept known as the "Good Rule". This states that if you have a good musician, a good microphone, good equipment and a good engineer behind the desk, you'll get a good recording.

Seems simple, right? A chain, to switch metaphors, is only as good as its links.

This common-sense principle can apply to conservatories, too. There are, we would argue, four main factors that influence the longevity of a conservatory (leaving aside flood, fire and your neighbour's football). But as in music recording, you need all four for a good result.

The first is the materials used. Modern uPVC windows have a life expectancy of between 20 and 25 years. A glass or polycarbonate roof should last longer. And a tiled roof can last as long as 50 years.

These, however, are estimates that manufacturers use to cover their backs as much as to inform customers. A window or roof can last much longer if you maintain it properly.

This is the second link in the chain. The best materials in the world won't last long if you don't clean and repair them when necessary. Life has a way of filling your prized possessions with gunk – and if you don't act quickly, it can harden and create structural faults.

Thirdly, the lifespan of a conservatory is affected by its location. Of course, a big reason for getting a conservatory is to harness the elements – to see the sun flood through the windows or hear the patter of rain on the roof.

But weather, as we know, is both friend and enemy. If your conservatory is too exposed, sun, wind and rain can wear it away and reduce its lifespan.

Finally, there's your installer.

How can your choice of installer affect the lifespan of your conservatory?

It's no exaggeration to say that your choice of installer can dramatically affect the lifespan of your conservatory. It's the difference between planting a tree in nourishing soil and sticking it in a trough of pig swill.

Work with a good installer and you can look forward to a durable conservatory made with good-quality materials. But go with a less reputable installer and you could be creating problems for yourself in the long-term.

It's a bit like buying a used car. If you do your homework, you can get a great set of wheels at a bargain price. If you cut corners and rush to a decision, you could end up with a dud that needs repair work.

Whether you're buying a used car or a conservatory, the risk is the same. The savings you made on the initial purchase will be wiped out by the money you have to shell out for repairs down the line.

We'll say it again: your choice of installer is at least as important as the materials used or where in the garden it's installed. It's at least as important as keeping it clean.

But this is all easier said than done. How can you know that your installer will do a good job? For our money, there are five things to look for.

Five things to look for in a conservatory installer

1. Versatility

If you went to a restaurant and they had just one dish on the menu, you might take your custom elsewhere. The same goes for conservatories.

Conservatories come in a range of styles, from classic Victorian models to orangeries to lean-tos. Does your installer have the type you're looking for? If not, shop elsewhere.

2. Experience

With installation work, there's no substitute for experience. Aside from anything else, an experienced team can fix problems as they arise in a way that greener workers just can't.

So when you're looking for an installer, check to see how many times they've been around the block. It could save you a packet in the long run.

3. Service with a smile

The most important thing is to get the job done. But wouldn't you prefer to work with a company that treats you with politeness and respect? This is especially important if issues arise on either side during the installation process.

4. No jargon in the garden

When people don't know what they're doing, they tend to hide behind jargon. This is true whether they're explaining construction methods to you or engaging in a spot of upselling.

If you feel like someone is trying to dazzle you with details, look elsewhere. Chances are, they're bluffing – and they won't deliver when it matters.

5. Aftercare

You want your conservatory to last. Working with an installer that provides aftercare is a simple way of maximising the chances of it happening.

Final thoughts

A conservatory can be a wonderful addition to a property. But before you sign on the dotted line, make sure you're working with a reputable installer. That way, you can be sure it will have a long and healthy life.

What causes window condensation (and how to stop it)

Mon, 27 May 2024 20:38:03 GMT

Discover the most common causes of window condensation and how to keep it out of your home.

Window condensation can be annoying at best and harmful at worst. It's perfectly understandable that you might want to get rid of it and put things in place to prevent it from occurring again.

That's why we've created this guide. We'll show you what causes condensation and how to stop it from forming on the inside and outside of your windows.

Why does window condensation happen?

Condensation occurs when warm, moist air from indoors meets a cooler surface, such as a glass window pane.

Glass is up there with the coldest home materials. That's why water vapour makes its home there, condensing to form that foggy effect. Then, if there's excess moisture, it rolls down the pane in droplets before collecting in the seals or on your windowsill.

Top causes of window condensation

Lack of home ventilation, poor insulation and high humidity levels can make condensation on inner windowpanes worse.

Condensation inside double glazing, meanwhile, can be caused by deteriorating window seals and faulty spacer bars that stop absorbing excess moisture. In cases like this, the only answer might be to fit brand-new, high-quality double- or triple-glazed windows .

The dangers of window condensation

What starts off feeling like a nuisance can quickly turn into damage to your home, dangerous mould growth and the health concerns that come with that. These can include respiratory issues, weakened immune systems and skin problems.

Top tips on how to prevent window condensation

Ready to say goodbye to window condensation? Try these top tips to help you banish the damp wetness from your windows once and for all.

How to prevent condensation on the inside pane

1. Step up your ventilation

When warm air can flow in and out of your house, condensation becomes less likely. There are several ventilation strategies available, including:

Opening windows , especially at nighttime if it's not too cold. This allows condensation-causing moist air to evacuate the building, reducing humidity in your house.
Ventilating built-in cupboards and wardrobes with devices like airbricks and vents. You can also leave the door open a smidge to prevent hot air from brewing inside and causing condensation.
Installing extractor fans in bathrooms and kitchens. These devices swiftly deal with excess moisture from these potentially steamy rooms and prevent condensation from reaching windows and other glass surfaces.

2. Take control of humidity levels

Certain activities in the house can increase condensation-causing humidity in the air. Here are some problem activities and their solutions:

Drying clothes indoors can cause humidity levels to rise. If possible, dry clothes outside on the line or in a dryer to reduce air moisture levels in your home.

Cooking on the hob. Now, we know this one can be hard to avoid, so at least try to cover any pans while cooking. This will prevent steam from escaping into the room and onto your windows.
Taking long showers. We know, we know… they feel so good. However, taking long showers without cracking a window or having adequate ventilation can lead to window condensation.
Plants. Perhaps surprisingly, our little potted pals release moisture into the air. To help prevent them from contributing to condensation, move them away from windows.

To help keep the perfect moisture balance in your home, you could also consider investing in a dehumidifier or two.

3. Insulate your windows

Single-pane windows are renowned for condensation. This is one of the reasons double-glazed windows were invented – as well as keeping us warm, they help to reduce moisture build-up.

Double glazing works by keeping an air gap between two window panes. This air gap forms a barrier that shields the interior from cold temperatures outside.

So, if you have some single panes knocking around and are suffering from condensation, it may be time to upgrade them with some double glazing.

4. Step up your seal game

Make sure you get a sealant you can trust to keep the moisture out and last. Look for the following features to ensure optimum sealing power:

Durability. You want a sealant with staying power – one that acts as a long-lasting barrier against cold air from outside.
Flexibility. The sealant should allow for movement within the window frame.
Suitability. You need to seal windows from the inside and the outside so make sure your sealant is up to the job. Some can be used indoors and outdoors so you won't have to buy two separate products

How to prevent condensation inside the windowpanes

Get a professional in to seal

The main culprit of condensation inside your windowpanes is ineffective sealant. Sometimes, the best thing you can do is get a professional to seal your windows , as they will have the best and fastest technique.

This is especially important if you're sealing multiple windows.

Replace your double glazing

If your double glazing is accumulating condensation in between the windowpanes, it may be best to replace the window parts that are letting in the moisture or get brand-new uPVC replacement windows .

When is it time to replace my foggy windows?

If you follow all the tips above but still have condensation, it may be time to get some brand-new windows. There's only so much you can repair before it's more beneficial and cost-effective (in the long run) to get new windows.

You also need to make sure the people fitting your windows do a good job to help keep any future moisture out from inside the panes and inside your house.

If you're looking for reliably fitted high-quality windows in Yorkshire, we can help here at Calder Windows. As the region's window and door specialists, we supply only the best products from trusted retailers, a professional fitting service and a 10-year warranty for all window installations.

8 of the best plants for a conservatory

Fri, 17 May 2024 15:14:40 GMT

Need some inspiration for your conservatory? Discover some of the best plants for creating unique vibes.

Is your conservatory ready for a change? Want to bring the outside inside? A conservatory can be a beautiful place to host guests, read a book or just generally relax and enjoy yourself.

And with some well-placed plants, it can become even more of a haven in your home.

Have you thought about how houseplants could enhance your space? Maybe you have and your conservatory is already a blooming marvel.

If so, then read on for even more inspiration to complete your dream indoor garden room. If not, then get ready to transform your conservatory (and your mood!) with our handy guide to conservatory plants. We'll help you create a beautiful indoor oasis, whatever vibe you're aiming for.

Why add plants to your conservatory?

Conservatories are the perfect environments for housing plants that would usually struggle in our temperate climate. The lack of frost and an abundance of light will help your plants thrive.

How wonderful to surround yourself with exotic flora… It might just evoke distant memories of holidays in the sun.

We've categorised our plants by style, but feel free to mix and match however you like. Remember: this is all about creating a space for you to enjoy and indulge in – so get creative and get green!

Vibrant and colourful

If bright colours make you smile then you might want to consider these plants with cracking foliage.

1. Mandevilla (rocktrumpet)

Mandevilla is a climbing plant that originates from tropical Central and South America. It boasts beautiful blooms in a spectrum of colours, including white, pinks and popping red.

Install some trellis and let the plant climb to get the best view of Mandevilla in all its flowery glory.

2. Cyclamen

Cyclamen is widely found on sale during autumn and winter. It should flower for around six weeks, so its delicate petals are sure to brighten up your Christmas conservatory.

This pretty perennial comes in peach, lilac and magenta flavours. Or maybe you want to go traditional and stick with bold bright scarlet? Whatever you choose, Cyclamen will bring a spot of colour to your conservatory during the darkest months.

3. Plumbago auriculata (Cape leadwort)

Plumbago auriculata is sure to turn heads. Its intense blue, unscented flowers look beautiful as they climb up the walls of a conservatory.

You may recognise this plant from holidays in the Med, where Cape leadworts are plentiful and enjoy the warm temperatures. However, they won't survive in a UK garden so they're perfect for your garden room.

Just be aware, they are toxic to humans if ingested. They're safe for pets, though – so no worries about Doggo.

Scorching desert

Is your ideal conservatory somewhere you can sip on a margarita? (Or watch out for rattlesnakes?)

Or maybe you've visited the Mojave or Sahara and want to relive the drama of the landscape and bring the desert home.

Whatever the reason, a desert-inspired conservatory is a great idea if you want a total change of scenery. Here are a few ideas to get you started.

4. Agave americana (century plant)

This is the large, spiky plant you may have seen in a hot house at a botanical garden.

Century plants make a bold statement – but you need the space to house one, so choose carefully.

You can be sure of a long-term companion when you invest in Agave americana . Older plants will produce yellow flowers but won't reach full maturity for 10 to 20 years.

5. Aloe vera

You might be more familiar with Aloe vera as an ingredient in your favourite soap or face cream. That's because this plant produces a stick gel that's known for its myriad health benefits.

Boasting antibacterial and antioxidant properties, it has been used for centuries to treat sunburn, cuts and scratches – and some even use it as a remedy for heartburn.

The good news for conservatory cultivators is that Aloe vera looks positively charming too.

6. Cacti

There are many types of cacti that will thrive in your conservatory.

If you want a dramatic vibe, you might choose one or two varieties to dress your space. This is ideal for creating a stark and authentic look with big, bold leaves.

Or go wild and experiment with lots of types to see what happens. How sharp are their spines? Which ones will flower?

A cactus can become a friend – and you may well find yourself lightly brushing your new succulent to remove dust. Or why not sing it a song?

Cool, calm and collected

If a sanctuary is what you're after then look no further than these cool houseplants. They'll help you create a calming place in your home where you can relax and unwind.

7. Stephanotis floribunda (Madagascan jasmine)

After a tough day, there is nothing better than sitting down, taking a few deep breaths and just sinking into a state of relaxation.

The delicate fragrance of jasmine is ideal for these moments of peace. The delicate white flowers last for a few months and will provide your conservatory with a natural air freshener that you can enjoy every day.

They can be tricky to grow, though – so do your research and be careful to give them the care they need.

8. Money plants

There's an abundance of so-called money plants, all of which will thrive in your conservatory. The Chinese money plant has coin-shaped leaves, while the jade's leaves are fleshy and succulent.

We hope they bring you luck and prosperity!

Top tips

Think about spacing your plants at different heights to create a dynamic and inviting atmosphere where your eye can flow through the space fluidly.
Do your research. Make sure you understand how to care for your plants and think about the flowering seasons to maximise colour.
Some plants may be toxic to humans or animals. Get to know which plants are dangerous and think about what might be a wise choice for your home.

Now you know all about which houseplants might suit an indoor space, why not let Calder Windows take care of all your other conservatory needs?

16 unique ways to decorate a bay window

Fri, 10 May 2024 07:24:53 GMT

Get creative and decorate your bay window. Here are some unique design ideas to get you started.

Bay windows can be one of the most attractive features of a house – and they're a real joy to decorate. Here are just a few ideas to get you started.

1. Create a cosy reading nook

Here's a great idea for any bookworms out there – or for anyone who loves to lounge in the sun while relishing a good magazine.

Turning your bay window into a snug reading nook is easy. Simply get a comfortable window seat or sofa along with some plush cushions and throw pillows. Lay out a soft blanket too, if you like.

You've now got a perfect place to relax by the window with your favourite book or magazine. Consider installing some standing or floating bookshelves next to the window so you've got some choice reading materials nearby.

Now you're all set to lose yourself in a good book while the world drifts by. (Or why not take a well-earned nap instead?)

2. Build a beautiful indoor garden

If you've got green fingers, consider turning your bay window into a haven for houseplants. Install some shelving and you can surround your window with gorgeous green leaves. A small console table also works well.

Try creating a display with plants of different varieties and sizes. Add some hanging planters and window boxes to maximise space and create an amazing alfresco effect in your living room. You'll love the serenity this creates – and your plants will love the ample sunlight.

3. Carve out a functional workspace

More and more of us are working from home these days – and one of the biggest challenges this creates is finding a useable workspace that's free from clutter.

A great way to create a stylish and productive home office is by placing a floating desk near a bay window and then adding a comfortable chair. Pair it with task lighting and attractive stationery to complete the transformation.

You might want to consider facing your desk towards the room and treating the window to avoid harsh light.

Is there a better place to sip your morning coffee while checking emails than a lovely bright bay window? We don't think so.

4. Install wood blinds

A great way to calm your room is to install window blinds – especially if you're planning to use your room for work. Wood blinds come in a variety of colours and wood stains. They can provide an aesthetically pleasing way to block out excess light from outside.

5. Get a settee

If you don't want to invest in a custom, built-in window seat, a curved bench settee is a great way to accentuate the contours of your bay window. Bay windows make ideal seating areas – and a settee is a great way to make the most of this without breaking the bank.

6. Make a conversation corner

Get a couple of upholstered chairs to place by the window and stick a side table between them to create the perfect little nook for chatting away with a pal.

You could add a nice rug and perhaps a floor lamp for some pleasant ambient lighting and – voila! You've got the ideal space to catch up with an old friend.

7. Create an art display

Turn your living room into an art gallery by hanging up your favourite paintings, prints and sculptures and putting them in stylish frames. You could put up hanging rails or a gallery wall system to show off your favourite works of art, enhanced by natural sunlight.

8. Ramp up the vintage charm

Classic charm, shabby chic, retro style – whatever you want to call it, you can embrace a vintage aesthetic by furnishing your bay window with antique décor pieces and furniture. Check out antique shops and flea markets to find great second-hand pieces for very little money.

Why not add a chaise lounge or armchair, a drinks cabinet, ornate mirrors, lace curtains, or other retro-inspired accessories to bring some old-world charm to your room?

9. Get creative with DIY stained glass

You can really make a window pop by creating your own stained-glass panels. You can use glass paint or adhesive window film to achieve a stained-glass effect or even try your hand at traditional stained-glass techniques for a unique period look.

Or, if you're feeling brave, let your kids have a go at adding some colour. (You might want to use removable window paint or pens for this.)

10. Install Roman shades

Roman shades are a stylish way to draw attention to your bay windows. Individual Roman shades that stack up also have the benefit of making your windows seem taller. They work by drawing the eye up towards the shades.

11. Add curtains

Curtains can add depth and cosiness to a room and are a classic way to decorate bay windows.

Think about what colours will work with the colour scheme of the room. You might also want to consider thick curtains if noise or bright streetlights are an issue. Or, to block out direct sunlight on bright days, install sheer curtains behind your heavier drapes.

12. Create a breakfast area

Bay windows are a great location for a breakfast table. Use a simple bench or a dining table with chairs to create a bright space in which to enjoy your breakfast tea or coffee. Go for a simple design that will not block too much light from entering the room.

13. Save it for seasonal décor

Celebrate the seasons by incorporating seasonal decorations. Here are some ideas:

Twinkling lights, a Christmas tree and decorative snow for winter
Blooming sunflowers and Easter eggs for spring
Beach vibes with seashells and driftwood for summer
Spooky skeletons, cobwebs and pumpkins for Halloween

If you have kids, they'll love decorating the windows with you – and you can get truly creative without having to commit to any decorations for too long.

14. Paint an accent wall

Painting the area around your bay window can add a sense of space and vibrancy to your home.

Consider your current colour scheme before you decide on a colour for your feature wall – dark, earthy tones often work well to make your room appear dynamic and exciting. Or you could go for a jazzy wallpaper to really make the room pop.

15. Go bohemian

Add some bohemian flair to your room by decorating your window with eclectic textiles. Think colourful rugs, embroidered throw pillows, patterned curtains and unique bits of furniture, like an eye-catching coffee table.

Beaded curtains or string lights around the window can add to the boho vibe too – as can potted succulents and decorative floor lamps.

16. Make a little Zen retreat

Create a serene and peaceful retreat inside your own home by adding a bit of relaxing Zen design to your bay window.

Floor cushions and a meditation bench can help you achieve some inner peace, as can soothing scented candles. Natural materials like bamboo and stone can also help create a calming atmosphere. Finally, why not install a small indoor water feature to create a quiet centrepiece?

How to adjust uPVC doors

Sat, 04 May 2024 15:31:22 GMT

Is your uPVC door looking a bit skew-whiff? Learn how to adjust rattling, catching, and draughty uPVC doors.

Need to adjust a uPVC door but don't know where to start?

It's one of those jobs you know you can probably do yourself – but you just need to take a few minutes to learn how. That's where we can help.

Check out our DIY guide below and you'll learn how to adjust uPVC doors so that they don't rattle, catch on the floor or let a draught through.

Remember: before you adjust your uPVC door, check if you have a manufacturer's guarantee or warranty. You don't want to invalidate it unnecessarily and the manufacturer may provide aligning services.

Why do you need to adjust uPVC doors?

These doors typically get used a lot, so it's not uncommon for the doors to drop or become loose in their hinges as time goes by. This is why you need to check your hinges regularly to see if any adjustments need to be made and keep your door in the right position in its frame.

How do you know a uPVC door is misaligned?

Here are some essential checks to identify if and where your door is misaligned:

Check the corners of the door – their mitres must line up with the mitres of the doorframe.

Get a spirit level and place it on top of the door to see if it's straight.

Open the door a bit and look at the lock side to see if the gap between the door and the frame is consistent from the bottom to the top.

How do you know if the door is warped?

Cheap uPVC doors can be prone to warping.

You can usually tell a door is warped when it meets the frame at the top and bottom but leaves a gap in the middle. Replacing it is probably the best thing to do in this situation.

If the door meets the frame at the top but leaves a gap at the bottom, it may simply need a hinge adjustment to get it back to its usual shape.

What hinges do uPVC doors have?

If you've discovered your uPVC doors are out of alignment, you must identify which type of hinges are fitted. Each type needs to be adjusted in a slightly different way.

Butt hinges

These old-school hinges look like rectangles with a hinge from a smaller rectangle in the middle.

They're usually found in early designs of uPVC doors but are still common nowadays. The adjustments vary depending on how old the hinge is, with some allowing for lateral adjustment, lateral and vertical adjustment or no adjustment whatsoever.

Flag hinges

These hinges look a bit like – you guessed it – flags.

Modern uPVC doors usually have flag hinges. Luckily for you, if you have one, these hinges give you the most control over door adjustments. You should have no trouble whether you need to move the door closer or further away from the frame.

T hinges

These hinges look very similar to a flag hinge, but the "flag" part is in the middle rather than on top. It can be adjusted in the same directions – vertically and laterally.

How can I adjust uPVC doors?

Here's how to adjust each type of hinge listed above and the tools you'll need to do so.

Essential tools

Get yourself the following tools in your kit:

Allen keys (also known as hex keys)
Phillips head screwdriver
Flathead screwdriver

How to adjust flag hinges on uPVC doors

First, you need to get to the adjustment screws.

Look for a lateral adjustment screw behind a plastic cap over the hinge mechanism. Loosen the two Phillips screws inside the hinge to remove this.
Use a flathead screwdriver to pop the caps. These caps may be at the top and bottom of the hinge.

Now for the adjusting…

Use an Allen key to rotate each screw once or twice right the way around to test the adjustment. Turn them slowly until you get your desired position.

The top screw on the hinge can usually help you adjust the height of the door up to 4.5 millimetres.
The side screw on the hinge can normally help you adjust the door from side to side up to five millimetres.
The bottom screw on the hinge can usually help you adjust the compression up to two millimetres.

How to adjust T hinges on uPVC doors

Follow the steps above for a flag hinge. The only difference is that a T hinge may not have an adjustment for compression.

How to adjust butt hinges on uPVC doors

If there are two Phillips screws on the side of the butt hinge, you can usually adjust the door laterally by around two millimetres. Simply turn the top or bottom screw to loosen it so you can move it side to side.
Take the cap from the top of the hinge and expose the screw, then use an Allen key to adjust the hinge up and down.
If you can see a screw right in the middle of the hinge, this will also need to be loosened before you adjust the pin.

How to adjust uPVC doors to prevent draught

Screws, latches, and hinges can loosen and cause misalignment as time goes by. The solution? Adjust your door latch so the lock and latch fit together nicely. This helps keep the door primely positioned in its frame.

You'll also want to read the tips above on general misalignment and adjust the hinges to help prevent rattling.

How to adjust uPVC doors that drag on the floor

A uPVC door that has dropped on the side of the handle can usually be fixed like this:

Keep the door closed.
Use an Allen key to adjust the screw on the door side of the hinge.
Turn it fully around once or twice before testing to see if it drags, tweaking until you can open and close the door in a smooth motion.

Door replacement FAQs: the answers you need before work starts

Fri, 26 Apr 2024 08:00:00 GMT

Need a replacement door? Got questions? Don't worry – Calder Windows has the answers you need.

So, you fancy a new door.

Maybe your old one is looking a little tatty or doesn't chime with your décor. Or perhaps you'd prefer an upgrade because yours is lacking in the safety and security department.

Whatever the reason, picking a new door can be tough – and the questions that arise when you finally decide to buy one might come as a surprise.

When is the right time to replace a door? Do you also have to replace the frame? And what's this FENSA business, anyway?

Don't worry if you feel a little overwhelmed. We're here to help.

Here are some of the most frequent questions we're asked when it comes to replacing doors.

When should I replace a door?

We're no stranger to fighting the elements here in the UK. As the weather batters our beautiful landscapes, it can also wreak havoc on our homes.

On top of that, you have to consider general wear and tear. We use our doors every day – and over time, they really do take a slamming.

Jokes aside, doors will eventually start to look their age. Consider replacing them when you start to notice significant signs of damage, faults in the locking mechanisms or a general reduction in "kerb appeal".

Can you just replace the door and not the frame?

Yes, you can replace a door without the extra work of replacing the frame.

This option may be slightly more cost-effective. However, to go down this route you need to ensure your new door measurements are 100% correct for the new door.

Your frame also needs to be in good condition as it's now going to be housing another door for years to come. If you're unsure whether your frame is in good enough condition to remain in place, Calder Windows can help you determine the best course of action.

Do replacement doors need building regulations approval?

First, let's clear up a common misconception.

Installing a new door will rarely need planning permission . Unless you're building a brand-new porch or other significant structure, you can go ahead and change your door without seeking permission from your local planning authority.

However, your new door will have to comply with building regulations .

This is where things can get complicated. The regulations that apply depend on factors like whether the door is glazed, how much glass is used and whether the size of the opening is being changed.

The good news is that you don't have to worry about any of this if you use a FENSA-approved fitter. More on that below.

Do replacement doors need FENSA?

It isn't a legal requirement to get a FENSA certificate. However, it can be more appealing if you eventually put your property on the market.

FENSA certifications prove that the replaced part (your new door) complies with building regulations, is energy-efficient and is registered with the local council.

You'll only be supplied with a FENSA certificate if you use a FENSA-approved installer.

Here at Calder Windows, we are FENSA-approved. This means that any doors, windows and roof lights purchased from us will come with the correct certification.

Are all composite doors the same?

In short, no.

Standard composite doors have an average depth of 44 millimetres and a foam filling. They're extremely lightweight and can be decorated in various colours thanks to the fibreglass skin.

There is an alternative to the standard design: the solid-core composite door. This type has layers of timber within, which make it tougher and more robust than your standard composite door. The average depth of a solid-core door is 48 millimetres.

What style of door should I go for?

Ultimately this comes down to personal taste. With so many options on the market, we realise it can be a tough decision to make.

To make that all-important decision a little easier, we recommend visiting our showroom and looking around at the different doors available. Our friendly staff are ready to help you make your choice.

You should also take a moment to decide on a colour scheme – because, let's be honest, no one wants to end up with a door that doesn't match the rest of their home.

This decision is particularly important as not all styles of doors come in huge ranges of colours.

The final thing to consider is this: how much light do you want to come from your front door, if any? Nowadays, there are doors available with huge panes of glass in the middle, to the side and at head height.

You can, of course, opt for a door that lets in no light at all.

Window replacement scams and dodgy sales tactics to watch for

Mon, 15 Apr 2024 08:00:04 GMT

We always deliver an honest service – but do other firms? Learn how to avoid common window scams.

At Calder Windows, we have spent the last 30 years building a reputation for excellent customer care and service. As FENSA-approved fitters, we can issue a certificate of quality with every installation.

Superior quality will always sell itself – and there is no place in our family business for cold calling or pressure selling. And we want our customers to feel completely confident in their choices, so we always give a cooling-off period for every sale.

In short, you can trust us. However, it's a sad fact that the window replacement trade has a darker side. There are rogue traders out there who operate without honour or integrity.

To help you stay safe and protect your hard-earned cash, let's pull back the curtain on some of these scams and dodgy sales tactics.

The most common window replacement scams

The most effective scams are based on a kernel of truth. Take these two examples…

The government grant scam

You get a phone call or a doorstep caller excitedly informing you about government grants for double glazing and offering to check if you could be eligible.

The truth is there are a couple of government-backed schemes*, but only in rare circumstances will anyone qualify. Isn't it nice of this kind person to offer to find out if you're eligible?

No! This is the first part of the scam.

The eligibility questions will be designed to get important details about you and your finances – information that can be used to hack your passwords or bank account.

Part two of the scam is when they delightedly congratulate you on passing the eligibility check and ask you to put down a deposit for your new windows. They say you'll be able to claim this back from the government scheme. That's a lie! You'd be paying a fraudster.

* Phone your local council to check the eligibility criteria for the ECO4 scheme or the HUG2 scheme.

The pay-up-front-for-a-discount scam

You agree to a quote from a doorstep salesperson who seems to work for a recognisable company.

You're asked to fill in their very comprehensive questionnaire about you and your finances so they can offer you the best finance plan. However, there is an alternative, they say.

They can give you a very substantial discount if you'd be prepared to pay in full – upfront and in cash – for a "one-day-only deal".

They seem legitimate. Their paperwork has a company name you recognise – and that discount would make a real difference. Tempted?

Unfortunately, the paperwork is false. If you signed up, you'd be handing your money and all that personal information over to criminals.

Sadly, caught up in the moment, many have lost a significant chunk of their savings this way.

Dodgy sales tactics: what to look out for

Attention-grabbing offers and discounts

You agree to have a salesperson call to receive a quote for an advertised discounted line.

Unfortunately, you won't get it – usually because that line doesn't actually exist. What they will do is confide in you about the poor quality of the discounted windows. You can expect to hear all sorts of reasons why they, personally , wouldn't touch them.

Next, they'll show you a completely different selection that they tell you is far superior. These are, of course, more expensive. "After all", they say, "you only get what you pay for!"

Actually, these are the company's standard windows but they're trying to trick you into paying more than you should, believing you're getting a superior line.

An inflated initial quote

This salesperson is in for the long haul. They'll make an evening appointment, for your convenience and then tell you about the two-hour drive it took to get to you.

You're already being set up to feel pressured not to waste their time and effort.

Every window in your home will be inspected and carefully measured – but what they're also doing is looking for clues from your home and your conversation to find common ground. From births to bereavements, health issues to holidays, you can bet they've experienced it too.

The more empathy they can generate, the harder it will be for you to say no.

Finally, it's time to calculate the quote. They'll begin typing into their laptop with an air of happy expectation. Soon though, you see a frown appear, the pursing of lips and perhaps an exaggerated exhale.

This little pantomime will be followed by some spurious reason why your windows are going to be more expensive than expected. Then they drop that massively inflated price and watch your shocked reaction. Gasp!

What follows is pure theatre. Over the next hour, this salesperson will work tirelessly on your behalf to find discounts, make little compromises and, finally, make a private phone call to his boss.

The idea, of course, is that after all that effort to get the quote so greatly reduced, you'll find it impossible to turn down and will gratefully sign the contract. Too late, many find out their "discounted price" was actually more than most standard prices.

Pressure selling at its sleaziest.

How to protect yourself

Only deal with traders who are members of BM TRADA, FENSA or CERTAS. This means their work complies with building regulations and is covered by an insurance-backed guarantee that kicks in if they're not compliant or the company goes bust.
Get multiple quotes to compare prices and quality.
Look at online reviews – or ask family and friends for recommendations.
Avoid evening visits. Have salespeople call during office hours – then you can easily call their company to do an ID check.
Never pay money or sign a contract straight away. A reputable company will send you a full written quotation confirming the product, including installation hardware, labour, any equipment hire costs and insurance together with genuine offers or discounts. They will never offer a "one-day-only" deal.

At Calder Windows, we sincerely hope you are never the victim of any sort of scam or pressure selling. But just in case, check out the Which? guide to getting your money back after a scam .

What are trickle vents and what do they do?

Fri, 05 Apr 2024 07:42:14 GMT

Installing new windows? Find out what trickle vents are for and whether you need them in your home.

You might not have heard of trickle vents – but don't feel bad if you haven't. Many houses don't have them, and if they do, they're unobtrusive and usually located at the top of the window frame.

However, they're great little devices. Trickle vents can help improve air quality and dry out dampness or mould, allowing us to maintain a comfortable and healthy home life.

They're essential in modern houses, which are designed to be airtight, but can be fitted to older buildings to perform just as well.

So, they're great. We get that. But what exactly are they?

What are trickle vents?

A trickle vent is essentially a very small opening in windows and doorways that continually lets in air, even if the window or door is closed. These ventilators allow a small but constant airflow, which can help prevent excess moisture from building up and creating mould.

Why do we need ventilation?

It's critical to have ventilation in any healthy living space. Buildings are becoming more energy efficient and windows and doors are now more draught-proof – and that all comes at the cost of fresh air inside the home.

Normal day-to-day activities like showering, cooking and cleaning clothes can produce a lot of airborne moisture. If moisture is trapped inside the home, it can cause mould to grow, which can be very harmful to your health.

If air is constantly circulating into and out of your home, this moisture is displaced and mould doesn't have an opportunity to develop. While there are other solutions for background ventilation, trickle vents are a cheap, simple and effective option.

Do I need trickle vents?

According to UK building regulations, trickle vents are mandatory if your currently installed windows already have them. So, if you're replacing windows that have trickle vents installed, your new windows will need some too.

Trickle vents are required for all new properties and for any windows installed in an extension. However, homes using mechanical ventilation and heat recovery, or other methods that meet building regulations, don't need trickle vents. Listed buildings are also exempt.

Can trickle vents be retrofitted?

Yes, it's possible to add trickle vents to existing windows and doors. This might be something to consider if you're experiencing problems with condensation in your home and don't have other adequate forms of ventilation.

They can be tricky to install – retrofitting is usually achieved by drilling through the existing frame. So, it's best to speak to a professional beforehand to make sure you get the most effective installation possible.

It's important to note that trickle vents will always work better when built into a window frame.

How do trickle vents work?

Trickle vents usually use a small, canopied vent that allows a small amount of fresh air inside the building.

They're located in the frame of a window or door and have a cover that can be opened or closed. They're usually acoustically designed so they allow the least amount of sound from outside into your home. Most are covered with an insect net.

What are acoustic trickle vents?

There's always something of a trade-off between letting fresh air in and keeping noise out. This can be an issue in areas with high traffic or near brownfield sites.

Luckily, installing acoustic trickle vents can help block out noise and soundproof your home while still allowing a steady flow of fresh air.

Can trickle vents be closed?

While trickle vents can be closed, it's advisable to keep them open to allow continuous air inside your home, even in the winter months.

During cold days, there's less ventilation than normal – and activities like drying clothes inside and cooking can build up moisture. That's why it's best to keep them open to allow fresh air inside – unless you have another form of background ventilation.

Where are trickle vents on windows?

The most common method of installing trickle vents is the through-frame method. This is where the vent is fitted into the top of the frame and features a staggered design that minimises draughts.

Other forms of trickle vents include the over-frame design, where the vent is fitted over the top of the frame, and the glazed-in design, where the vent is fitted into the glazed area between the sealed glass and the frame.

What are the benefits of trickle vents?

Trickle vents offer numerous benefits to your health and quality of life. They significantly improve air quality, which is important as stagnant air can lead to pollutants and allergens. They help minimise condensation, a common issue in the UK which is often damp and cold. Preventing mould is essential for a healthy and comfortable home, as mould build-up can cause respiratory problems, as well as damage to the property.

It's also important to comply with UK building regulations to ensure the property is safe for residents. Some people may prefer the look of window frames without a trickle vent – but today's vents are hard to notice and are generally integrated seamlessly into the frame.

Trickle vents offer far more security than having to open windows to ventilate your home. They're also energy efficient: they offer a good amount of ventilation to balance out the lack of air in well-insulated modern homes.

Any change of internal temperature from a trickle vent is fairly marginal – and if you're away from home for a long period, trickle vents will help to keep your home fresh.

Finally, they can be closed in winter if other forms of ventilation are used. This offers a good amount of control over energy usage in your home.

Trickle vents are an essential part of installing new windows. Calder Windows offers bespoke window and door solutions for your home, including state-of-the-art trickle vents and our revolutionary triple-glazed window system. For a quick, competitive quote, don't hesitate to get in touch .

Conservatories and extensions on listed buildings: a guide

Tue, 02 Apr 2024 07:33:11 GMT

If you live in a listed building, there are additional things to consider when planning an extension. Learn more.

So, you want to add a new extension or conservatory to your home. Perhaps you need some extra room or simply want to catch a bit more sun during the summer months.

Sounds simple, right? It's the kind of addition that thousands of homeowners make each year.

But if you live in a listed building, things start to look a whole lot more complicated.

Where do you start? Do you need planning permission? Should you use special materials, designers or engineers? And how much say do you have on what it will look like?

Well, we're here to guide you through the process from start to finish. We'll cover what it means for a building to be listed and explain how to get high-quality, compliant designs that suit the character and listing requirements of your home.

What are listed buildings, exactly?

First, what does it all mean? Listed where ? And with whom ?

Historic England is the public body that holds and maintains records of all listed buildings. Known as the National Heritage List for England (NHLE), this document lists around 500,000 buildings that are considered historically important. Among them are homes, shops, libraries and churches.

The list is freely available to the public and you can quickly and easily search it online. Its purpose is to protect the legacy of these snapshots of the past for future generations.

An entry on the NHLE is a badge of honor and many owners of listed homes are rightly proud of their special building. Listed status could also increase your property's value.

What are the listed building grades?

Listed buildings are categorised into three grades depending on their historical importance. These grades range from Grade I (the most important) to Grade II (the least important).

Grade II buildings are, says Historic England , "of special interest". This is the most common category with around 92% of listed buildings falling under this classification.

The Grade II* category covers "particularly important buildings of more than special interest". Grade II* is Grade II with bells on, basically. Buildings in this category are a little more unique or rare.

And then we have Grade I, which is reserved for buildings "of exceptional interest". Wear this with pride as only 2.5% of the listed buildings in England find themselves in this tier.

Why do buildings get listed?

One of the main reasons is age. Any home built between 1700 and 1840 will most likely be listed. If your home was built before 1700 and is still standing in anything like its original form then it's almost certainly on the list. (And probably pretty high up the list.)

What is covered by listing status?

A graded listing will typically cover the entire building, its footprint and its interior. This includes the interior layout, dividing walls and sometimes even furnished fittings and décor.

The listing can also include parts of the garden – particularly at the front of a home – if it's considered an important part of the building's character. The same goes for adjoining or outlying buildings such as brick-built sheds or outhouses.

It's important to remember that anything excluded from your listing will be mentioned on the NHLE entry. For example, a brick-built shed added at a later date may not form part of a house's listing credentials and may be detailed as an exclusion.

But beware: if a feature isn't mentioned, you should assume that it's covered by the listing.

You can check what's covered on your property over at Historic England . Alternatively, you can contact your local planning authority.

What sort of planning permission or consent do I need to make changes?

To make additions or changes to the features of your listed property, you must first apply for listed building consent from your local planning authority. This works similarly to the planning application you would make for a normal home extension (and, indeed, planning permission may still be required).

You must be granted listed building consent before starting your building project. A local authority should give a response to your application within eight weeks.

Be warned that carrying out works to a listed building without prior consent is considered a criminal offence. Not only could you be prosecuted, but you may also have to undo any work carried out.

Unauthorised works on a listed property can also throw up problems later down the line if you try to sell.

The build and its design

There are 101 reasons why you might want to add an extension or conservatory to your home. But what does it mean when your property is listed? Are there restrictions on what it can look like or the building materials you can use?

Well, yes. But a little consideration before your planning application should mean these issues are dealt with before they have a chance to arise.

The key here is to consider the property's setting. What will your extension or conservatory look like when complete? It's important that it doesn't dominate the building's appearance and should take up less than a majority share of the building's total footprint.

An extension is also much more likely to win approval if it sits to the rear of your property rather than at the side or the front. The rear of a building is typically considered less architecturally important – and, of course, it doesn't affect the house's appearance from the street. Permission for front-facing extensions is rarely given.

The style of the conservatory or extension doesn't need to mimic historical examples but it does need to match the character of your home. That's why a bespoke build is usually the best solution for a period house.

A considered, tailored design can allow classic features to sit in harmony with modern building techniques. It can accentuate the charm of historical architectural design, while providing all of the perks of today's buildings, such as better insulation and reduced energy costs.

Ultimately, though, the decision is down to the local planning authority. For more information on the application process and any local particulars, refer to your local authority's website.

Happiness has many roots, but none more important than security. (Edward Stettinius Jr.)

We lock our doors to keep ourselves, our valuables and our loved ones safe. But what do we know exactly about these silent guardians in which we put so much trust?

Perhaps, like many, you have simply inherited the locks on your doors and windows from a previous homeowner. If this is the case, your first question might be, "How do I know if my locks are the right quality?"

Well, if your locks are all Yale 3-star Euro Cylinders, then you can relax. These locks boast the highest security rating available and are endorsed by the UK Police in its Secured by Design scheme.

How do I know if I have Yale locks?

Look for the British Standard Kitemark found engraved on the faceplate, the metal part of the lock that can only be seen when the door is open.

Of course, Yale locks all carry this mark. But 3-star Euro Cylinders will also be stamped with a diamond symbol with three stars above it.

Why do Yale locks have such a good reputation?

You know those movie scenes where the Action Hero bursts through a front door with one impressive kick? Or where the secret agent casually gets to work with her lock picks and gains entry in a cool 30 seconds?

With a Yale 3-star Euro Cylinder lock, those scenarios stay firmly in fantasy.

It's all about the precision-engineered cylinder. Unlike the cylinder in lesser locks, it's highly resistant to all common forced-entry methods. That includes snapping, picking, drilling and bumping (hammering a screwdriver into the front of the lock).

In fact, Yale is so confident in the strength and resilience of this lock that it offers a £1,000 guarantee against it being snapped in a forced break-in.

How do Yale locks work?

The part we push our key into is actually a little barrel that rotates inside a cylinder as we turn the key. As the barrel rotates, it pulls back the door latch, allowing the door to open.

The clever part is the line of six tiny holes drilled through the bottom of the barrel into the base of the outer cylinder. An extremely strong steel pin sits in each hole. This protrudes up through the corresponding hole in the barrel and prevents it from rotating.

The pins sit on tiny springs so they're able to be pushed down. The barrel can only rotate if all the pins are pushed back through the holes at the same time by the teeth on your key.

However, the pins are set at different lengths, so the contour of the key has to precisely match the different heights of the pins as you push it into the barrel. Only then will the pins be pushed down far enough to allow the barrel to rotate and the door latch to disengage.

This design is the original pin tumbler cylinder lock that became synonymous with the name of its inventor.

Who invented the Yale Lock?

Linus Yale Jr. was the son of an accomplished and innovative locksmith, Linus Yale Sr. In 1850, at the age of 29, Linus joined his father in the family business. He took one of his father's earlier inventions and then perfected and patented it. The Yale lock was born.

Interestingly, Linus Jr. took inspiration from an ingenious wooden locking system used by the ancient Egyptians, 4,000 years ago.

The Egyptian lock featured a wooden bar that was attached to the door with a bracket. This bar could slide into a hole in the door frame.

As the bar slid forward, wooden pins dropped down from the bracket into holes in the top of the bar. This prevented the bar from being pulled back, effectively locking the door.

To unlock the door, you needed something that looked very much like a large wooden toothbrush, which was slightly angled up at the end. The "bristles" were wooden pegs arranged in a pattern. This could be inserted into a cut-away in the wooden bar below the pins.

The arrangement of the pegs corresponded precisely to the pattern of the holes in the bar. This meant that the pegs could be pushed up into the holes to push the pins upwards out of the bar. When the pins were in position, the bar could be slid back out of the door frame and the door would be released.

The number of holes in the bar and their pattern would be different for each door so only the wooden key with the matching pattern of pegs would work.

What's next for Yale locks?

Over the past 180 years, Yale has consistently added more features to its locks in an effort to produce the most secure products possible. It's poetic that a company that took inspiration from the ancient world is now one of the leaders in smart home technology.

Enter the Yale smart lock. This is a keyless, electromechanical lock that includes all the security features you expect from Yale – but with the addition of Wifi or Bluetooth control.

This is home security on an entirely new level. Yale smart locks can be controlled from a smartphone app, so you never have to fumble for your keys again. This also means you can lock your door remotely, use virtual keys and receive notifications whenever a household member leaves or arrives back home.

How can I upgrade my locks?

As we've seen with those enterprising Egyptians, feeling secure is a fundamental need that quite literally spans millennia.

Calder Windows is here to fulfil that need. We only supply windows and doors that are of superior quality and ensure exceptional security. That's why we use Yale door locks in all our composite and French doors – and a multipoint reverse-action inline locking system for our uPVC and casement windows.

Can you build a conservatory without foundations?

Fri, 08 Mar 2024 09:00:00 GMT

Thinking of building a conservatory without foundations? Learn why it's not the best idea in our article.

So you're thinking about adding a conservatory to your home. Great idea! A conservatory is a fantastic way to add extra living space to your home without the expense of a full extension.

Modern conservatories are not only extremely versatile but also very secure and allow for a space in your home that can be used for pretty much anything.

However, if you're strapped for cash you might be looking for ways to save money. Could you maybe build a conservatory but skimp on the foundations?

Building your conservatory without a foundation is theoretically possible – but it would be highly risky. Foundations are integral to any structure and conservatories are no exception.

It might seem like a great way to save money but building your conservatory without suitable foundations will cost you more money in the long run as you fix the never-ending problems that will result – we're talking damp, uneven floors and subsidence.

If you go to the expense of building a conservatory, you want it to last the lifetime of your home. For this reason alone, it's important to take the necessary steps to make sure it's well-built.

What foundations does a conservatory need?

For your conservatory to live up to its potential, it needs to have some basic requirements for its foundations. These include building on a level, solid and damp-proof base.

Let’s dig a bit deeper (pardon the pun) to get a better sense of why conservatory foundations are essential.

Foundations are the basis for any structure as they provide stability and support. They're essential for bearing the weight of the conservatory and help to withstand the environmental pressures that the structure will be put under.

If your foundations are properly laid, they can prevent structural damage and ensure your conservatory remains a lasting and functional space for your enjoyment.

In the case of conservatories, a solid foundation is needed more than ever. Unlike traditional buildings that have solid walls, conservatories usually have large panes of glass which make them more susceptible to stress and movement.

If a conservatory lacks a properly built foundation, the actual weight of the conservatory could cause the ground underneath to settle unevenly or shift altogether. This in turn could lead to leaks and, worse still, structural damage.

Correctly laid foundations will prevent your conservatory from sinking and shifting over time. They can provide stability against wind, rain and soil movement and keep your conservatory safe and sound under external pressures.

Could you compromise and use a shallow concrete slab or pad?

Some may think that building a shallow concrete slab or pad would be sufficient. But while it may provide a small level of support, it lacks the depth and stability of a true foundation.

Over time, this could cause the conservatory to shift. And without proper reinforcement, the concrete pad or slab can crack under the conservatory's weight, leading to costly repairs or even collapse.

How are conservatory bases constructed?

Conservatory bases are usually built by digging a trench in the ground to the depth required. This is then filled with concrete.

For some conservatories, piling rods or steel reinforcements may also be required to add strength to the foundation.

On top of the concrete, there are layers of hardcore, membrane and scree.

Hardcore is a solid material like rocks or stone. It gets crushed up so it can be laid on top of the concrete foundation. The hardcore is spread evenly to provide a level base. At least 150 millimetres is the recommended depth for the hardcore level within the foundations. This is compacted and then a layer of sand is added to create an even surface.

A membrane is a special layer of damp-proof material that channels water away from your foundations and provides the primary waterproofing layer. This ensures any moisture which naturally occurs in the ground is not able to rise through the foundations.

Scree is your final layer of foundation. After the final pour of concrete and reinforced steel, the scree (which is a mixture of sand and cement) is then poured, levelled and smoothed into place using a levelling board. This provides a smooth floor and base for your conservatory to be built on.

All of these measures help ensure the solidity and stability of your conservatory. Skipping a stage puts both it and your safety at risk. It's just not worth it. Make sure you get your conservatory installed by those in the know.

What are conservatories made from?

A conservatory's walls and roof are made from glass and the frame is typically made from uPVC, aluminium or wood.

What's the difference between a conservatory and an extension?

The simple answer is "the amount of glass". For a building to be classed as a conservatory, at least half of its side walls must be glazed and at least 75% of its roof made from a translucent material.

Everything you need to know about sash windows

Mon, 04 Mar 2024 08:49:53 GMT

Calder Windows specialists in uPVC sash windows. But what are they, exactly? Learn more today.

Think of sash windows and your mind might be whisked away to a quaint Georgian property in rural England, nestled in a perfectly pruned garden, sunlight gleaming off of its many window panes.

But what are they exactly? Where did they come from? And are they still in use today?

They are in fact still being manufactured and not just for old houses or restoration projects. This guide should provide you with everything you need to know about the who, what, when, and why of modern sash windows – be it for the renovation of your stately home or the finishing touches on a new build.

Where are they from?

Sash windows are closely associated with ye olde England but in fact are believed to have been invented in Europe in the 16th century. They became popular with English architects sometime around the early 1700s.

They made quite a mark, remaining the people's favourite throughout Georgian, Victorian and Edwardian England. Since then, there have been many changes to the shape, style and construction of both glass and window frames – but the sash window style has outlived them all.

What makes a sash a sash?

Unlike modern-style casement windows which open outward on a hinge, sash windows are opened by sliding them vertically (and sometimes horizontally) within the frame.

"Sash" is a term for the glazed slab which sits within a grooved track in the window's outer frame. When this type of design was first introduced from France, sash was simply a nickname given to the window section of this new build type.

Today, we refer to the whole window style as sash. It's used to describe any window that doesn't open and close on a modern hinge system but instead uses weights or balanced springs within the frame, allowing the smooth travel of offset panes.

This style of window is easy to slide open and will stay balanced in the position you set them to thanks to the spring or weight mechanism hidden in the frame. Sash windows can be opened from the top, bottom, or both.

But are they just for old buildings?

Well, no – in fact, sash windows can give an elegant and classic look to a wide range of houses old and new. And with a huge range of styles to choose from, we can help get the perfect match for your home as well as match an existing design for when the time comes to replace old for new.

How do I know if I have sash or casement windows?

Now you know what a sash window is, you may be wondering what a casement window is, and how to tell the two apart.

A casement window uses hinges instead of a sliding action to open and close. Most modern-style windows are casement-type windows (they're just not referred to as casement windows all that often). They can open fully, and are hard to force open as the lock is hidden in the frame.

Do sash windows need wooden frames?

Not at all. At Calder Windows, we carry a huge range of uPVC framed sash windows, allowing you to have the timeless look with all the benefits of modern building materials: double glazing, energy efficiency and high levels of security.

These elegant windows have a smooth opening action and are excellent when it comes to draught exclusion. Unlike wooden-framed windows, they're a doddle to maintain. We're so confident in the build and install quality that all of our uPVC sash window installations are covered by a 10-year warranty.

When will a sash window need replacing?

All good-quality windows are designed to keep out draughts and rainwater. A tell-tale sign of terminal wear is when your window frames leak rainwater or let in a draught.

Why uPVC?

uPVC (or unplasticised polyvinyl chloride) is a material made famous for its strength and weather-resistant properties. But that's not all. Here are a few other things that uPVC windows have to boast about:

Security. uPVC is highly durable and resistant to impact, making it very difficult to damage or break (unlike wooden frames)
Energy efficiency. uPVC is the most energy-efficient option, helping to keep the inside of your home cool in summer as well as locking in the heat in winter.
Noise reduction. uPVC is built specifically to provide high levels of sound insulation and can reduce outside noise levels by up to 40 dB.
UV resistance. This means that your frames won't perish under direct sunlight.
Rot resistance. With uPVC, you don't need to spend much time on maintenance. This is in stark contrast to wooden frames, which tend to need replacing every five to 10 years.
uPVC doesn't rust, corrode, warp or flake. When it's in, it's staying in. That means your window mechanisms will work smoothly for life.
Pest resistance. uPVC doesn't harbour pests such as termites that can live in and feed on wooden window framing.
Weather resistance. These frames are durable and suited to all weather types, even coastal wind and rain.

Final thoughts

Sash windows are a characterful and timeless choice that suits houses old and new.

At Calder Windows, we believe that our uPVC sash window range is a match made in heaven for a variety of buildings. The unique open and close mechanism means this window style outperforms its competitors on both ventilation and view.

Our sash windows are available in a huge range of styles, sizes, finishes and glazing options meaning we can cater to your project, taste and budget.

How windows and doors can help tackle noise pollution

Fri, 01 Mar 2024 15:38:34 GMT

Reduce the noise pollution in your life. Find doors and windows to help keep your home a haven of peace.

When you think of pollution, what comes to mind? Floating plastic islands in the middle of the ocean? Dense cities with a thick, never-clearing haze of smog?

How about excessive noise?

Noise pollution doesn't make many headlines – but it's still a major environmental issue. In fact, the World Health Organization (WHO) recognises it as the second-largest cause of health problems after air pollution.

Why is it such a big problem? Is there anything we can do to reduce the noise around us?

This article will help answer these questions while exploring ways you can eliminate noise in your life and improve your well-being.

Why is noise pollution a problem?

Populations are swelling, cities are expanding and industrial activities are increasing. The result: noise is amplifying and we humans – as well as the animal kingdom – just can't take it.

So, whether you spend your Saturday afternoon listening to Mozart or cursing your neighbour as he trials his new pneumatic drill, it's worth keeping a close ear on volume.

Prolonged exposure to noise over 85 decibels is considered harmful to human hearing. For the record, that's about as loud as a hairdryer or smoothie blender.

Moreover, the WHO considers any sound over 65 decibels to be a potential source of noise pollution. That means anything louder than normal human conversation.

What does it do to the human body?

Hearing loss is just one of many health issues linked to high noise levels. According to the European Environment Agency, "environmental noise contributes to 48,000 new cases of ischaemic heart disease a year as well as 12,000 premature deaths".

How can something you can't see or touch be responsible for so many deaths? Studies have shown that high levels of noise interfere with sleep and can cause stress-related illnesses and high blood pressure.

No doubt that makes sense to you. We've all been annoyed (probably more than once) by the music from a rowdy late-night party or the thrum of traffic outside. Oh, and don't forget about next door's dog who just won't stop barking. It's stressful – not to mention anti-social.

We all agree that excessive loud noise is bad for us – and we all want to avoid it. But what's the solution? While we can choose to avoid loud concerts or seek out a peaceful park rather than the commotion of the city, we can't escape the noise surrounding our homes.

Or can we?

How can I leave the noise outside my home?

To understand what we can do to curb noise pollution, it helps to understand how sound works.

Sound waves travel through the air by vibrating air particles. Just as wind creates waves in the sea, sound creates waves in the air.

These waves can also travel through objects – and if the sound is loud enough, our ears can register the vibrations. However, it's much harder for sound waves to travel through objects like walls than through air. As a result, the denser the object the sound waves have to travel through, the more energy they lose and the quieter they become.

Thankfully, there are solutions that can help you reduce the noise outside your home so the external cacophony of the world doesn't impinge on your sanctum sanctorum.

What are some of these solutions?

Double glazing

Nowadays, the majority of us enjoy the benefits of double glazing. Not only does double glazing help keep the heat in but it also works to keep the noise out.

How does it do this?

As the name suggests, double-glazed windows have two layers of glass. Between those two panes of glass is a space filled with gas. These layers create a barrier that sound waves struggle to get through.

Over time, however, the seals around our windows can begin to perish and may allow noise to filter through. Also, if your windows have blown (become misty on the inside), then the layer of gas between the two panes of glass is no longer doing its job and has become ineffective at keeping noise out.

So, even if you have double glazing, it's important to check that it has been well-fitted, the seals haven't perished and the glass hasn't blown.

Triple glazing

If two layers are good then – you guessed it – three layers are even better.

Not only is triple glazing great for keeping in extra heat, but the extra insulation from the additional layer of glass and gas will also reduce noise.

It is important to note, however, that triple glazing and double glazing are not specifically made to eliminate noise. So, while they should reduce noise by an appreciable amount, it might be worth considering acoustic glass if you're really suffering.

Acoustic glass

Investing in acoustic glass is an option for particularly noise-affected homeowners.

We say "investing" because acoustic glass is more expensive than double or triple glazing. However, if your shut-eye is being disturbed that much by the noise outside, acoustic glass could work wonders for your health and well-being.

Casement windows

We've covered the glass in your windows – but let's not forget the frames. The type of frame you choose will make a difference to noise pollution levels.

Remember, we don't want any air leaks. Leakage, bad. Seals, good.

This means casement window frames are a good choice as they provide better noise reduction than sash window frames. This is because the pressure seals help to prevent air leaks.

Composite doors

"What about doors?", we hear you ask.

While composite doors are not specifically designed to prevent noise, the nature of their construction means they're no slouch in the noise-reduction stakes.

Composite doors are made with a densely packed insulating layer. As we know, the thicker the barrier for sound waves to pass through, the more energy they lose and the quieter they become.

This means composite doors provide multiple benefits. They promise better thermal performance, greater security due to their strength and the bonus benefit of noise reduction because of their thickness.

Ensuring windows and doors are installed properly helps prevent the air leaks that heighten noise pollution. That's why the installer you choose is just as important as the products they install.

How to choose the right window style for your home

Mon, 12 Feb 2024 08:58:19 GMT

Your choice of windows has a big impact on the look and feel of your home. So, just how do you pick the right style for your needs? Find out in our guide.

There's no two ways about it: windows play a pivotal role in the look and feel of your home. It can be hard to choose a style that ticks all the boxes.

Not only have they got to be visually appealing, but they also need to be energy efficient and meet the unique needs of your home and its occupants.

If you're in the market for some new windows and are suddenly having an internal battle because this isn't something you've considered, then worry no more.

We've put together a list of things to keep in mind when making your decision – from understanding window styles to lifestyle and budget considerations.

Casement windows

Casement windows are popular for a reason. Not only are they attractive, easy to operate and available in a range of colours and finishes, but modern varieties are also very energy efficient and are made of high-quality uPVC.

Their enhanced ventilation and wide viewing area make them a sound choice for thousands of homes up and down the country. They're customisable, come in all shapes and sizes and – best of all – require minimal upkeep.

Tilt-and-turn windows

A modern engineering marvel, tilt-and-turn windows look great and are seriously practical.

Their intelligent design allows you to tilt the window inwards to let air flow through your living space. Alternatively, you can create an "indoor-outdoor" feel by opening the window all the way.

They're available in a range of unique glass and colour options and are an absolute dream to keep clean and maintain. What's not to love?

Sash windows

A timeless classic with a modern twist, contemporary sash windows offer the best of two worlds. Our uPVC range combines a period look with the modern functionality needed for a safe and secure home.

These elegant windows are fitted with a smooth opening mechanism and are purpose-built to keep out draughts. Unlike their Victorian counterparts, however, they're easy to keep clean.

If that's not enough to tempt you, they're available in a range of colour and glass options to ensure we suit your taste to a T.

Bay windows

Picture this: it's Christmas time. Your decorations are up and the tree has taken pride of place in front of the bay window.

From the outside, it's a winter wonderland. From the inside, the sight is no different. Bay windows can add a classic, stand-out centrepiece to any home. With their unique way of highlighting the smallest of details, they're certain to make a statement.

If your home's architecture suits the style of a bay window, you'd be making a mistake to not consider this option.

With huge glass panels offering great energy efficiency and bags of natural light sweeping through your living space, it's a no-brainer.

uPVC vs aluminium

As if choosing your new windows wasn't hard enough, you now need to choose your preferred materials.

uPVC and aluminium share many of the same advantages. They're both extremely safe, energy efficient and require minimal maintenance.

One difference that you'll probably notice right away is the price. Aluminium windows are a little more expensive than uPVC. However, they're also longer-lasting and have a unique, contemporary look that some people prefer.

Typically, uPVC windows are more popular due to their affordability, fantastic efficiency and easy cleaning. Both options are available in a range of colours and designs and are made to measure for your home.

Double glazing and triple glazing

We've all heard of double-glazed windows, right? Well, what about triple glazing?

Double-glazed windows have worked their magic for years – and if you've ever gone from single-glazed to double-glazed, you'll know what a big difference they can make.

Double glazing can help with noise reduction, energy efficiency, security and the value of your home, to name just a few of its benefits.

All of the above is increased when you introduce extra panes of glass. So, as you might expect, triple glazing is like double glazing on a bodybuilder's diet.

Not only does triple glazing offer all of the same benefits of double glazing – and then some – but it can also reduce energy bills by 40% thanks to its exceptional energy efficiency.

Better yet, our triple-glazed windows are made with extra-thick, 40-millimetre units to trap heat more effectively and really make a dent in those ever-rising energy bills.

Are you debating whether triple glazing is worth the extra cost? In this instance, we would say "absolutely." With a 40% reduction in energy bills, we're sure the windows will pay for themselves in no short order.

5 common window problems with simple solutions

Fri, 09 Feb 2024 08:59:17 GMT

Are you experiencing problems with your windows? Don't despair just yet – there may be a simple fix. Learn about 5 of the most common in our guide.

One of the pleasures of working in the window business is that you don't need to sell the concept, just the product. After all, no one needs convincing that windows are a fundamental part of your home or that a good-quality window is better than a bad-quality window.

Still, you'd be surprised at how many homeowners and renters neglect their windows. Most of us are on top of washing, ironing and cleaning, but windows? Someone will probably come around with a squeegee eventually.

This means many homes fall prey to common window problems – problems that typically get solved by ringing a maintenance worker.

We're not passing any judgment here. Life is quite complicated enough without adding "become a dab hand at window maintenance" to your daily agenda. Nevertheless, these problems can be frustrating, especially if you're unclear about what the source is.

The good news is that most of these common problems have simple solutions. Armed with these, you're likely to tear out less of your hair in the future.

First up: draughts.

1. How to get rid of a draught

Are you feeling a chill in winter that seems to be coming from the window? Or are your windows fogging up? It's probably down to an issue with the seal.

This is the rubber strip that's placed either between the frame and the wall or between the frame and the glass itself.

Getting rid of a draught isn't just about comfort, of course. It's also about thermal efficiency, which is important both environmentally and financially. At the end of the day, you don't want to be overspending on energy because of a problem that has an easy fix.

If there are gaps around the frame, block out the cold air with caulk or silicone sealant. If the gaps are between the window and the wall, you should look into weather-stripping – another material that's used to create a seal.

In both cases, it can be a DIY job or you can hire a window repair specialist . Job done.

2. How to fix stiff windows

If you can't open or close your window without a fight, you've probably got a problem with the hardware.

It could be that the hinges are stiff. An easy way to diagnose this is by tightening and loosening the hinges' screws and seeing if that makes a difference.

It could be that the window is snagging on the frame. Check that the runner is free from obstacles and give it a spray down with a lubricant.

Or it could be that the frame has warped. If so, it needs sanding down to allow for easy opening and closing.

Still not sure? It might be time to call an expert .

Window hardware is a surprisingly complex field thanks to the multitude of different windows on the market. A sash window, for instance, has different hardware from a casement window.

Unless you want to take a crash course in window repair, your best bet is to call in a specialist. They'll be able to quickly identify the problem and offer solutions. But simply knowing that hardware is the problem already gives you a head start.

3. How to clean mouldy frames

If your window frames are mouldy, chances are that you've got condensation. This is a perfect breeding ground for mould to spread.

As with all household mould, there's a long-term solution and a short-term solution. If you've got dinner guests and need to spruce up the window, or if you've started to notice that you're breathing in the mould, you can get a powerful spray and give it a good scrub.

If, however, you want to make the problem go away for good, you may want to invest in a dehumidifier. This sucks the moisture out of the air and prevents mould from proliferating.

There are other steps you can take to minimise mould. Perhaps the simplest is to open the window or windows in the room where you're drying clothes, cooking or showering.

Mould is nasty stuff – bad for your health as well as your home's aesthetic. Don't let it spread!

4. How to deal with discolouration

This is an issue that tends to affect older uPVC windows. If your window is turning off-white or yellowish, it could be because of prolonged exposure to sunlight, fluctuations in temperature and humidity, or exposure to cigarette smoke. Either way, you need to get a gentle cleaning solution and rub the problem away .

5. How to repair rotten or cracked window frames

Wooden window frames can rot – and, in the long run, this can make them difficult to operate.

If the rot is really bad, you should get a specialist in. But if it's relatively minor, you can nip it in the bud by removing the rotten wood and replacing it with wood filler.

Wood filler can also cover cracks. As with rot, however, home remedies only work with minor problems.

Final thoughts

Window maintenance isn't a priority for most people. But a faulty window is worth avoiding for all sorts of reasons – not just your personal comfort but also your bank balance and even your health.

In all of these scenarios, you have two options. You can tackle the problem yourself with home remedies – or you can get a professional in . The path you take will depend on the severity of the problem as well as your own skills.

It's also worth remembering that prevention is better than cure. If you regularly clean your windows and check them for any issues, you're less likely to be faced with problems down the line that require specialist help and a hefty bill.

However you choose to approach the upkeep of your windows, we hope this guide will help you to identify any problems and fix them with ease.

Decorative? Obscure? Etched? A guide to choosing door glass

Mon, 05 Feb 2024 09:00:04 GMT

Thinking of getting some doors with glass windows but don't know where to start? Learn about the most common options in our handy guide to door glass.

In western India, there's a village called Shani Shingnapur. It's famous for two things. First, it's home to the temple of the Hindu god Shani. And second, it has no doors.

That's right – not a single door or lock. Yet in spite of this remarkable state of affairs, there have been no reports of theft in the village.

In the UK, the idea of a house without doors is likely to strike fear into your heart. But doors aren't just about keeping out intruders. They're also part of exterior and interior design and, as such, can say a lot about their owner or owners.

Your front door, for one, is a key part of your property's kerb appeal. One way to give this a boost is to add a bit of door glass.

Yes, door glass can turn a nice-but-dull door into something that makes an impression. Something that reflects your own personality and style. Something that signals status. That's quite a lot for a simple block of wood or uPVC.

So really, what's stopping you from investing? Well, we can't read your mind, but we suspect it's one of two things: either your budget or a bad case of analysis paralysis.

We can't do anything about the financial side of things (aside from stocking affordable products). But we can help you to understand your options with a bit more clarity.

That's why we've put together this guide to different types of door glass. We hope it helps you to decide on a design that will wow your friends, neighbours and couriers.

But first: door glass – what's the big deal?

Why get a door with glass windows?

The main reason to get a door with glass panels – or to get glass panels fitted – can be summed up in a single word: light.

Increasing the amount of light that gets in your property is an easy concept to sell. Not only does it make your home feel more welcoming and spacious, but it can also help reduce your electricity bills and, some say, have a beneficial effect on your mental well-being .

But there's more to it than just giving your home a bit of extra natural light. Glass panels can create an elegant aesthetic, enhance your home security and improve your kerb appeal.

First, let's talk aesthetics. Door glass comes in a range of styles and adds an undeniable air of elegance to your home. Whether it's clear glass letting the light flood in or decorative glass creating gorgeous silhouettes, door glass can give your home a facelift.

Secondly, there's the security angle. This might seem counterintuitive – isn't glass easier to break than wood or uPVC? Well, not necessarily, as most glass panels these days are made from tough-as-nails toughened or laminated glass that takes an absurd amount of effort to shatter.

On top of this, door glass lets you see easily who's at the door – so you can make a better decision about who to answer to.

Finally, there's the question of kerb appeal. This is a significant factor in the value of your home and your ability to sell when the time comes. An attractive front door with glass panels or sidelights is an easy win where saleability is concerned.

Types of door glass

There are two main types of door glass: clear and decorative.

Clear glass is self-explanatory, but decorative glass is a broad church with a whole host of congregants. Some are patterned. Some are darkened. Some are partially see-through. Some are opaque. What they all have in common is that they're meant to be aesthetically pleasing and to change the look of the door.

In domestic properties, the most common types of door glass are frosted, etched and obscure glass. In commercial properties, you might see door glass that's been sandblasted or digitally printed with the company's logo or other text.

What is obscure glass?

This term refers to any type of glass that obscures or distorts the view. As such, it serves to improve privacy and is commonly used in bathroom settings.

Frosted glass is a popular type of obscure glass. It's glass that's been etched with acid, creating a pitted surface. Light can pass through – but you can't see much through it except for distorted shapes and silhouettes.

Other types of obscure glass include satin glass and sandblasted glass.

What's the difference between etched and frosted glass?

To look at, there's not much difference between etched and frosted glass. The difference lies in the extent of the treatment.

Etched glass has been sandblasted. This effect can be applied by degrees, from a light dusting to total opaqueness. Frosted glass is a term for etched glass that's fully or almost fully opaque.

What about doors that are entirely made of glass?

If you get a door made entirely out of glass installed in your home, you need to make sure that it's made out of toughened safety glass. Otherwise, you're putting your property at risk. Sandblasted glass is an option if you want to ensure privacy.

Glass doors are much more expensive than normal doors with glass panels – but they undeniably add a touch of class, as well as glass (sorry).

Conservatory furniture ideas to revitalise your extension

Fri, 02 Feb 2024 08:41:48 GMT

Looking for conservatory furniture ideas? We've got you covered. Explore 10 types of furniture that can turn your conservatory into a domestic haven.

Are you furnishing your conservatory and looking for inspiration? As with all kinds of interior design, it can be an overwhelming process as well as an exciting one. The sheer range of styles and products on offer can leave you with a headache induced by analysis paralysis.

One way to carve a path through this jungle of choice is to clearly establish what your conservatory's prime function is.

A conservatory can be a place to entertain or a place to unwind. It can be where you do your yoga or where you pot your plants. It can be a home office or a TV room. Keeping its function at the front of your mind can be helpful when investigating the plethora of options available.

In this article, we take a whistle-stop tour of ten ways you can maximise your conservatory's potential with furniture – from classic styles to more contemporary options.

1. Rattan furniture

One of the most pleasant things about a conservatory is the way it brings the outdoors in. A conservatory can be a liminal space, half-exterior, half-interior, combining the best of both worlds.

It's perhaps for this reason that rattan (and cane) furniture is such a staple of conservatory furniture. Those wicker-like plaits have a rustic yet sophisticated feel that can blend in seamlessly with your plants.

2. Modular sofas

Looking to host a large group in your extension? A modular sofa could be the way forward. It's a great way to ensure adequate comfy seating for large groups – and perfect for restlessly creative homeowners who want to try out different room layouts with ease.

Your sofa could be in any style, of course – from rustic greens and browns to bold, contemporary maroons and reds. It all depends on the vibe you want to create and the impression you want to make on your guests.

3. Victorian style

If you've got the budget, why not explore the wonderful world of Victorian furniture?

Conservatories date back to ancient Roman times, but they're inextricably linked to the Victorian era: a time when gardening was a middle-class status symbol and conservatories were built to impress.

Upholstered rosewood or walnut armchairs and vintage tables are undeniably classy and can pair well with your conservatory's steel (or steel-look) frame.

Such an aesthetic can be especially appealing if your conservatory is a place to entertain visitors as well as somewhere to unwind on your own. Of course, it doesn't have to be in a Victorian style. You could get a large dining table and chairs in any style to create a hospitable, elegant atmosphere – one enhanced, perhaps, by painting or wallpapering the retaining wall.

4. Swing chairs

This item of furniture goes by several names: the swing chair, egg chair or hanging chair. This free-standing, swinging cocoon is somewhere between an armchair and a hammock.

As well as being in vogue, it's ideal if you want a lightweight but comfortable piece of furniture that can be moved in and outdoors at the drop of a hat.

5. Lamps and other lighting

After hours, conservatories can be the perfect spot for a romantic meal or drink. Dim the lights, set a table lamp or floor lamp and perhaps fire up the wood burner or add some sparkling string lights.

The result? A cosy, intimate space to unwind in.

6. Benches

In Édouard Manet's 1879 oil painting In the Conservatory, a woman sits on a dark bench made of what appears to be wood. A man, possibly her husband, slouches darkly over its back. To their left is a vase of pink flowers. Behind them is a forest of plants.

It's a good look. Getting a bench in your conservatory can create a sense of vintage charm or, if you go for a Scandinavian-style wood bench, an air of contemporary minimalism.

7. Potting tables

If you're a keen gardener and primarily use your conservatory as an extension of your gardening life, why not set a potting table in the centre?

But conservatory plant life doesn't end there. You could add hanging plants to a pole on the ceiling or train climbing plants up the walls.

Conservatories give you plenty of scope to experiment with plants. Whether you want a lush jungle or something more homely, the conservatory can be a blank canvas for you to throw ideas at.

8. Create the illusion of space

One of glass's best properties is its ability to create space. A conservatory will always feel spacious thanks to the masses of sunlight it lets in. But one way of making your extension feel even bigger is to furnish it in all-white – especially if the frame is all-white too.

9. Window seats

If conservatories are good for one thing, it's sunlight. Getting a comfortable window seat lets you curl up like a cat in the sunshine. Moreover, window seats are ideal for patterned cushions and throws – accessories that can help put a personal stamp on your extension.

Finally, a window seat can be a great way to create hidden storage space – and as any homeowner will tell you, more storage space is not something to be sniffed at.

10. Rugs

Not strictly furniture, of course, but if you want your conservatory to be cosy rather than rugged, a rug can soften the space (and help keep your feet warm).

What's more, an outdoor rug in your conservatory can help bridge the gap between inside and outside.

Conclusion

One of the best things about conservatories is their versatility – a quality that's reflected in the wide range of furnishings available. Whether you want an indoor garden or an outdoor room, your furnishing choices can make a huge difference. We wish you all the best in your explorations!

U-values made simple (finally)

Fri, 12 Jan 2024 07:00:59 GMT

If you're shopping around for windows, you might have heard of U-values. But what do they mean? And why does it matter? Find out in our guide.

What are U-values? And why should you care?

If you've done a little research about home improvements or heating, you may have come across the term. You might have thought, "'U-value'? That sounds like a budget hardware shop" and left it at that. Perhaps you learned that U-values have something to do with heat efficiency – but then you hit a wall of science and algebra that only a megabrain could scale.

We get it. Type "U-value" into your friendly neighbourhood search engine and you're likely to get an explanation that looks something like this:

"To calculate the U-value of an object (in W/(m²K)), you must sum the thermal resistances of its individual layers (thickness divided by lambda value), while also taking into account the surface thermal resistances of its inside and outside elements."

If you understood that – great, welcome to Harvard. If not, join the club.

There's a reason why U-values are complicated. They were once the preserve of architects and construction engineers – building boffins with calculators and qualifications to spare. It's only fairly recently that they were used to market windows and the like.

So, to save your brain cells from self-destruction, here's an explanation for the rest of us.

What are U-values?

U-values measure the thermal resistance of parts of a building – like, say, a window or a wall.

In simple terms, this means it measures their effectiveness as insulators. In even simpler terms, it shows how good they are at trapping heat.

Why does this matter? Because thermal resistance matters for your wallet and the planet. When our homes trap heat effectively, our heating doesn't have to work as hard. As a result, we use less energy and spend less money lining the pockets of our energy providers.

Is bigger better?

U-values are a bit like golfing scores. The lower they are, the better.

This is because U-values show how quickly heat can make its way through a material. You want your window to have a low U-value because this means that heat gets through very slowly.

A high U-value, by contrast, promises poor insulation and fast heat transfer. In practical terms, this means you're paying to heat your garden as much as your home.

What makes a good U-value?

Unless you're familiar with U-values, it can be hard to know where "good" starts and "average" ends.

We could tell you, for instance, that solid brick walls tend to have a U-value of around 2 W/(m²K). But on its own, this is pretty useless. We may as well say that they score purple on the colour scale – or that they're very W, which is better than F but not as good as B.

To make matters more complicated, what makes a good U-value for a wall might not translate to a good U-value for a window. They're made of different materials and do different jobs – so we have to adjust our expectations accordingly.

However, things become clearer when we start making comparisons. Yes – the easiest way to get to grips with U-values is to take a leaf from WeightWatchers' book and compare befores and afters.

So, you have an uninsulated cavity wall with a U-value of 1.5 W/(m²K). Later, you call in the builders to add insulation. The insulated wall now boasts a U-value of 0.18 W/(m²K).

A quick calculation (1.5 divided by 0.18) shows you that the insulated wall is roughly eight times better in terms of insulation performance. Nice.

What about windows?

As a long-time window supplier and installer, we watch glazing U-values like traders watch the stock market. And we're happy to report that things are looking good.

Once upon a time, windows could take much of the blame for heat loss in our homes. A poor-quality single-glazed window can have a U-value as high as 5.8 W/(m²K). That's roughly three times as high – and three times as bad – as a solid brick wall. Ouch.

But hardly anyone uses single glazing anymore. If you buy a new window nowadays, it will almost certainly be double- or triple-glazed – and it will be specially designed to minimise heat loss and protect our wallets.

With high-quality modern double glazing, you can expect a U-value of around 2 W/(m²K). Much better.

Our triple-glazed windows take things even further. They use a revolutionary, extra-thick thermal shielding system to deliver better insulation than ever before – and have a U-value of 1 W/(m²K) to show for it.

This means our triple glazing is roughly six times more thermally efficient than some old-fashioned forms of single-glazed windows. That's good news for Mother Earth and Papa Bank Balance.

Is there an easier way?

U-values are complicated and they only show part of the picture. For instance, they don't measure solar heat gain – the amount of heat from direct sunlight that enters a room.

That's one reason why energy performance certificates (EPCs) are often better indicators of a window's thermal performance. Not only do they show the full picture, but they're also a whole lot easier to understand.

EPCs can be applied to a whole property or to an individual component of a property. They measure energy efficiency on a simple scale, ranging from E (worst) to A++ (best).

In the UK, windows have their own form of EPC called a Window Energy Rating. If you're shopping for windows, look for a colourful label marked "Window Energy Rating" or "Energy Window".

These labels are produced by various schemes and organisations, including the British Fenestration Rating Council (BFRC) and the Thermal Ratings Register.

You don't have to worry about who created the label though, because they all measure energy efficiency in the same way. They assign a rating based on the window's U-value, solar heat gain and effective air leakage – a measure of airtightness.

You won't see any new windows with a rating worse than C. This is because building regulations dictate that all newly installed windows must be at least C-rated.

To put things into perspective, our double-glazed windows achieve a rating of A or A+, depending on the type. Our triple glazing , meanwhile, meets the requirements for an A++ rating: the highest grade on the scale.

When do you need planning permission for a conservatory?

Mon, 08 Jan 2024 09:00:01 GMT

A conservatory can make a great addition to any home. But do you need planning permission to get one? Separate the facts from the fiction with our guide.

Are you thinking about getting a conservatory? It can be a great way to bring your house and garden together – and bump up the market value of your home in the process.

Once you've decided on a style and a design, you might find yourself wondering about the thorny issue of planning permission. Is this something you need to seek from your local authority?

The short answer is that you might. Some, but not all, homeowners need to get permission. It's important to know which camp you fall into as you risk receiving a fine if you press on without it.

What are the rules about conservatories?

Different types of constructions require different planning permissions. A conservatory falls under the same rules as a single-storey extension. Neither requires planning permission as a general rule.

However, there are exceptions.

You live in a designated area – for example, a conservation area, World Heritage Site or Area of Outstanding Natural Beauty (AONB).
Over half of the building's ground will be covered by the conservatory.
The conservatory will be on the side of the house or facing the road.
The conservatory will be higher than the house.
The conservatory will be wider than half the width of the house.
The conservatory will be over six metres to the rear of a semi-detached house or eight metres to the rear of a detached house.
The conservatory will be raised.
The original building is a terraced house or one that's already been extended.
The conservatory will increase your home's volume by more than 15% or 70 cubic metres (whichever is bigger).

We can boil these down to two main considerations – two big questions to ask yourself before you get the builders in.

The first is about your area. Do you live in a designated zone where construction is restricted?

Secondly, you need to think about the size of your proposed conservatory. Will it be unusually big or visible? If so, it's worth checking whether you can go ahead without permission from the local authority.

If you're unsure, your best bet is to check with your local planning authority (LPA). They will look to see if your project needs planning permission. There's also government guidance on the subject.

If none of this applies to you, crack on!

What happens if you need planning permission but don't apply for it?

If you fail to get the required planning permission, you could be fined. If it doesn't meet regulations, you could be forced to demolish it.

To take one example that made the local news, NAME REDACTED of Dewsbury built a single-storey side extension without permission and was ordered to pull it down by Kirklees Council.

The grounds on which the demolition order was made give some indication of what you need to take into account when thinking about planning permission. The extension, the council said, was "an incongruous development out of character with the main house".

Will your conservatory or extension stick out like a sore thumb, no matter how much you like the design? Then make sure you check the guidelines in detail before calling the builders.

Do you need planning permission for an extension?

The law says that homeowners can have an extension added to their homes without planning permission, so long as it meets building regulations. These projects fall under "permitted development rights".

Permitted development rights aren't all-encompassing. If you live in a flat, maisonette or listed building, you'll have to apply. The same goes for houses situated in conservation areas or AONBs.

What is a lawful development certificate?

If you build within your permitted development rights, your conservatory or extension is above board. But it can still be a good idea to apply for a lawful development certificate. If you come to sell your home, a lawful development certificate can demonstrate to potential buyers that the extension is compliant with regulations.

How long does it take to get planning permission?

Typically, it will take around 10 weeks for your local authority to weigh your application and reach a verdict. This consists of a two-week validation process and eight weeks of decision-making.

We say "typically" because the more complicated your plans, the longer the process will take.

It can be worth asking your local planning department for advice. Some rudimentary guidance is available for free. There's also the option to get "pre-application advice" for a fee.

What else do you need to check before getting a conservatory built?

Another important thing to establish before the builders start work is that your foundations are deep enough. If they're not, you're wasting your time and money!

What home improvements don't need planning permission?

Most of the time, you can add an extension, roof alteration, dormer, garage, hard surface or decking to your home without planning permission. As with conservatories, there are exceptions – and either way, you may need building regulation approval.

Final thoughts

Here at Calder Windows, we know that a conservatory can make an elegant addition to any property – and we can help you find the right style and design for you.

Most of the time, you can start work on a conservatory without planning permission. But if you live in certain designated areas or if the extension is going to be unusually large or incongruous, you may have to check the small print.

How are double-glazed windows made?

Fri, 05 Jan 2024 06:53:45 GMT

Ever wondered how double-glazed windows are made? The truth is more fascinating than you might think. Join us as we explain the nuts, bolts and argon.

These days, double-glazed windows are as common as double duvets or double entendres.

And while they do a very important job, they're unlikely to be the last thing on your mind before you nod off into dreamland. They're everywhere – but for many of us, they're also kind of just there .

So, let's kick things off with some congratulations. To you, the reader. If you've found this blog, you're part of an exclusive club – a club of inquisitive folk who, at some point or other, have wondered how double-glazed windows are made.

That deserves a pat on the back. Not everybody has that kind of insatiable curiosity.

Perhaps you've thought to yourself, "They can't just be two sheets of glass in a frame. There has to be an interesting story behind how they're manufactured."

And you'd be right.

The anatomy of a double-glazed window

Before we explain how double-glazed windows are made, let's cover what they're made of and how the different ingredients fit together. This will make everything easier to understand.

The anatomy of double glazing is pretty well-established at this point. Double-glazing manufacturers create things called sealed units. These are the core elements of double-glazed windows – and their design is more or less standardised across the industry.

Here's a cross-section of a uPVC sealed unit.

It might look complicated – and it is if you zoom in on all the individual parts. However, its basic design is very easy to understand. It consists of a uPVC frame, two panes of glass and a spacer bar. The frame and the spacer bar hold the glass in place and create an air gap between the two panes.

Typically, this frame sits within a larger frame, allowing the window to open and shut.

Simple, right? Different types of windows differ on the details – they might use different kinds of glass or vary the width of the spacer bar, for instance. But in essence, all double-glazed windows follow this basic design.

That doesn't mean that all double glazing is created equal, though. If companies cut corners at the manufacturing stage, you could end up with a window that underperforms in terms of heat retention. That's why it's really important to choose a reputable supplier that sources high-quality products from equally reputable manufacturers.

How is double glazing manufactured?

Double-glazed windows are available as made-to-measure units or straight off the shelf. In either case, the glass, frames and spacer bars are made to size and then assembled in a specialised facility.

It's not just a case of sticking the parts together, making a cup of tea and clocking off for the day, though. Modern double-glazing panels are not separated by air – they use a special type of inert gas called argon instead. And that argon has to get between the panes somehow.

There are two ways to achieve this.

The first is to assemble the parts, drill holes in the frame and pump the argon inside. This process is relatively simple and gets good results. The trade-off, however, is that a little air will inevitably get inside the sealed units before they're sealed off.

The second and more complex method is to use an argon-filled chamber. In this process, the sealed unit is assembled, save for one pane of glass. The half-assembled unit then passes through the argon chamber, where the final pane of glass is pressed into place. This traps the gas inside and ensures that the window is filled with all argon – and no air.

Finally, a sealant is applied around the edges of the glass to keep the unit airtight. It's now ready to fit into a frame and begin its new life as a full-fledged double-glazed window.

How do manufacturers prevent condensation inside the window?

Sealing off the window helps a whole bunch. This traps the gas inside and stops moist air from entering the gap between the panes.

Even so, sealed units often end up with a little moisture inside after the manufacturing process. This is because the panes of glass are cleaned before assembly – and they may still have a bit of water on them when they're fitted.

So, to prevent moisture build-up, the spacer bars are filled with a desiccant. This is a special substance that absorbs moisture from the air and helps prevent condensation from forming between the two panes of glass.

Have you ever bought a pair of shoes and found a tiny sachet of silica gel within the box? That's a kind of desiccant.

Double-glazing manufacturers, however, use desiccants that are specially designed for windows.

Why go to all this trouble?

Double-glazed units are precisely manufactured and carefully sealed to make sure that the argon stays in place for the life of the window.

But, you may be thinking, why bother? And why use argon, anyway?

Double-glazing manufacturers go through all this trouble for one simple reason: the glass isn't the most important part of a double-glazed window. It's what's between the glass that counts.

This air gap (or, rather, "argon gap") is what gives double glazing its heat-retaining superpowers. Heat has a hard time getting through the sealed gas between the two panes. This means that warm air stays in, cold air stays out and – fingers crossed – your heating bills remain manageable.

Argon is used because it's a bad heat conductor. It acts like a fur coat for your home, trapping heat inside and keeping you toasty on those cold winter nights.

In the old days, manufacturers didn't use argon. They used common-or-garden air. But nowadays, argon is pretty much the standard because it's a whole lot more effective.

In the industry, these kinds of argon-filled sealed units are known as "gas fills". If you order a double-glazed window nowadays, you can be pretty sure you're getting a gas fill.

Talking of ordering double-glazed windows, that's pretty much our "thing". Here at Calder Windows, we've installed windows in Wakefield and West Yorkshire for more than 30 years.

A guide to cleaning uPVC windows and doors

Tue, 02 Jan 2024 22:00:02 GMT

You've invested in beautiful new uPVC doors and windows. Would you like to keep them in showroom condition? Read on for top cleaning tips.

When fitting new doors and windows, there are many things to consider such as design, security, energy efficiency and cost. "Easy-to-clean" might be further down the list – but you'll appreciate its importance long after the windows have been fitted.

We all lead busy lives and anything that can save us time and money in the long term should not be undervalued.

As uPVC is a non-corrosive material, it doesn't absorb moisture. This means it's easy to wipe clean because, unlike wood, it won't rot, warp or splinter.

But let's be realistic: anything that's open to the elements will sometimes need a little more TLC to keep it in tip-top condition. Here's how to do just that.

Cleaning equipment

The beauty of cleaning a smooth surface is that you don't need an expensive box of cleaning products to maintain your windows.

A bucket of warm water with washing-up liquid, a sponge, a microfibre cloth and a brush (from a dustpan and brush set) is all the basic kit you need.

Additionally, white vinegar, a squeegee, a soft toothbrush, some scraps of old newspaper and a spray bottle will come in handy if you're planning a more thorough clean.

The cleaning process

Start by dry brushing away any cobwebs and insects.

Fill a bucket with a solution of warm water and a little washing-up liquid. Using a sponge, apply water to the whole area, starting with the frames and then the glass.

An initial sweep will immediately loosen the dirt, revealing any stubborn marks like insect droppings. Use a soft toothbrush to get into the corners and scrub these off.

A microfibre cloth (which is non-abrasive) will be useful here. It can remove these marks without scratching or damaging the surface.

Wipe off the water with a cloth or squeegee. Use a fresh cloth to dry the glass and wipe away residue and streaks.

To achieve streak-free perfection, use distilled water.

Alternatively, fill a spray bottle with one part white vinegar to four parts water. Spray the glass and wipes the panes in a circular motion with scrunched-up newspaper. The acidic composition of vinegar is effective in breaking down the film that can build up on the glass over time. It also makes for an ecological alternative to chemical cleaners.

Cautions

uPVC is porous and therefore can stain. Beware: some detergents have hidden colourings in them.

An internet search will suggest a well-known cream cleaner – but this is abrasive. So, while it has many uses, cleaning the smooth surface of a uPVC window is not one of them.

Anything that can cause scratches will damage the surface, dull the shine and make it more difficult to clean in the future as dirt will become trapped in the scratches.

So, on the banned list are:

Abrasive cleaning products
Bleach – or any cleaner with bleach in it
White spirit, which can stain white frames to brown
Solvents
Nail varnish remover
Scouring pads and wire wool
Scrapers and knives
Steam cleaners, which may damage the seals

Stick to washing up liquid and you'll have no problems.

Cleaning mould from your door and window frames

Sometimes a little bit more elbow grease is needed.

Mildew, mould, baked-on insect droppings or dead insects that seem to be welded to the window can pose a challenge.

All can be successfully removed with the same products as before – but you'll need a little more patience.

Use the same vinegar solution mentioned above. Spray the solution on the problem parts and wait for 10 minutes.

uPVC is water resistant, so the solution will sit on the surface and soften the offenders rather than soak into the frame.

Then, using your cloth and soft toothbrush, gently brush them away.

Do the frames need a little re-whitening?

White vinegar solution comes to the rescue again! Simply use the same process as before – apply the solution and give it 10 minutes or so to work its magic.

Remember the warnings we gave above. It might be tempting to use bleach but it won't produce the effects you might expect. Rather than whitening the window frames, it will make the discolouration worse and can damage the smooth surface.

Yellowing is caused by excessive exposure to UV light, so prevention is the key.

Wiping a window regularly with a vinegar solution will keep it looking fresh. This is especially important for south-facing windows.

Long-term cleaning and maintenance

We've focused so far on the maintenance of the frames and glass – but from time to time the other parts deserves some attention.

Open the windows and clean inside the frames using the same methods as before.

A toothbrush will be especially helpful here. It can help you clean hard-to-reach areas and the spots around the handles and hinges.

Inspect the seals for any signs of damage. If you find tears or fraying, get the seal repaired as soon as possible. If in doubt, contact your window installer for advice.

How can you stop them getting in the dirty in the first place?

Given that we live in quite a wet and windy country, we can't prevent windows from getting dirty. The best option is to carry out some quick maintenance between cleans, regularly dry-brushing the frames to remove loose debris.

Fill a spray bottle with a water and washing up liquid solution. Lightly spray the microfibre cloth (don't soak it) and wipe the glass clean. Taking just a few minutes to reduce dirt build-up means that a deep clean will be quicker next time.

All crawling insects a problem?

These type of insects dislike vinegar, so rinse out your spray bottle and fill it with your water-vinegar solution. Spray this around the edges of the windows to deter them.

A clean sweep

There's no doubt that uPVC doors and windows are easier and cheaper to maintain and keep clean. A regular cleaning routine will keep them looking fresh for years to come, enhancing the beauty of your home.

Here at Calder Windows, we've been fitting windows and doors for more than 30 years. If you're considering uPVC replacement windows , why not call in to our showroom and view our extensive range? Our friendly staff will be happy to advise you on the best products for your home.

6 of the most iconic windows in the world

Mon, 18 Dec 2023 09:00:03 GMT

New windows can work wonders for your home – but these examples take things to the next level. Discover 6 iconic windows from around the world.

Over time, styles have changed but one thing has remained the same: windows continue to be used as statement pieces, just as they always have.

Windows come in all sorts of styles and can have many functions – so it's not surprising that there are hundreds of outstanding and fascinating examples across the globe.

So, if you're looking for some inspiration for a new installation, look no further. We've compiled a list of six of the most iconic windows from across the world.

1. The Rose of the Apocalypse at Sainte-Chapelle, Paris

The Sainte-Chapelle is home to one of the world's most iconic pieces of art: the perturbingly named The Rose of the Apocalypse .

This spectacular stained glass window is composed of 15 panels arranged in the shape of – yes – a rose. Each shows a different scene from the life of Jesus.

It looks as vibrant and intricate as ever – but was constructed more than 750 years ago after being commissioned by Saint Louis.

The Rose of the Apocalypse is admired by visitors daily and will forever be a "must-see" destination for those looking to experience French architecture and art.

2. King's College Chapel, Cambridge

You'll find this beautiful Gothic chapel on the grounds of King's College at the University of Cambridge.

The chapel has multiple mesmerising details. However, the treasure trove of narrative windows is what we're most interested in.

The windows incorporate both religious and royal motifs and shine a light on the artistic advancements of England's Gothic period.

3. The Tiffany Dome at the Chicago Cultural Center

Opened in 1897, The Chicago Cultural Center is used by the mayor of Chicago when welcoming the President or other leaders and diplomats.

Since its opening, it has been a tourist hotspot. This is partly thanks to its star attraction: an enormous Tiffany glass dome.

Constructed and designed by Tiffany Studios of New York City, the dome measures 38 feet wide and sports a unique look. The glass tiles are designed to look like fish scales, while the apex of the dome depicts the 12 signs of the zodiac.

The centrepiece, though, is a delicate-looking chandelier that dangles from the very top.

4. The aquarium window at Chimelong Ocean Kingdom, Zhuhai

For this example, we head from one side of the globe to the other.

China is home to the spectacular Chimelong Ocean Kingdom, which boasts the world's largest aquarium window, according to none other than Guinness World Records.

This enormous window measures a staggering 39.6 by 8.3 metres. In case that wasn't impressive enough, the window is made from one acrylic panel – again, the largest in the world.

Of course, people are there to see the fish – not the window. The Chimelong Ocean Kingdom is home to 20,000 rare species, including several types of sharks and turtles.

This stunning build offers an insight into an underwater ecosystem and the opportunity to immerse yourself in sea life like never before.

5. The Pope's window, Vatican City

It wouldn't be a rundown of the most iconic windows worldwide without a mention of the Pope's window.

Ever since the 17th century, the Papal Apartments have been the official residence of the Pope.

The apartment building consists of several large rooms, an office for the Papal security, staff quarters, a medical and dental suite and – of course – the Pope's own study, which features the famous window.

Every Sunday at noon, the Pope can be seen at his window delivering a short speech followed by a prayer and blessings to spectators gathered in Saint Paul's Square.

This rich piece of Roman heritage has become a huge attraction for locals and tourists alike, all of whom are keen to experience this iconic event.

6. The Burj Khalifa, Dubai

Known as the tallest building in the world, the Burj Khalifa is famous in its own right.

Located in Dubai, UAE, this extravagant skyscraper stands at 829.8 metres – or just over half a mile.

Construction of the magnificent structure began in 2004, with external works finishing five years later. The builders then took a year to complete the interiors before the building opened its doors to visitors from across the globe in 2010.

The mastermind behind the Burj Khalifa is Skidmore, Owings and Merrill – an American architectural firm that also designed One World Trade Centre in New York City.

With more than 26,000 reflective glass panels, along with aluminium and textured stainless steel spandrel panels, this building represents modern-day architecture at its finest.

As well as looking great, the glass helps to protect the building – and its inhabitants – from the intense desert sun, extreme temperatures and strong winds.

It's been reported that it takes 36 workers three to four months to clean the exterior of the building. They use state-of-the-art equipment to ensure all 24,348 windows are sparkling clean.

Still looking for inspiration?

If stained glass windows and domes haven't fuelled your inspiration, then why not head over to Calder Windows? We can't construct a skyscraper but we can help you bring your ideas to life.

We've got a huge selection of statement windows, skylights and bi-folds in a range of designs and colours. And with more than 30 years in the trade, we have the experience you need to make your vision a reality.

A brief history of conservatories

Fri, 15 Dec 2023 09:00:01 GMT

Think of a conservatory and you'll probably picture a Victorian style. But conservatories have been around for centuries. Join us as we explore their history.

These days, conservatories make an elegant addition to any garden. They're great spaces to entertain friends and family or just chill out and watch the birds. And it doesn't hurt that they can add to the market value of a property too.

Conservatories have been around for a long, long time – but not in exactly the form you find them today. At the time of writing, a conservatory has to have glazing on at least half of its side wall and three-quarters of its roof to legally qualify.

But it wasn't always thus. We've come a long way since the earliest conservatories but one thing is constant: they've always been about adding a touch of class.

The earliest conservatories

In the 21st century, conservatories are for people and greenhouses are for plants. But this distinction is relatively recent. From the 16th century on, Britons have used conservatories for entertaining and growing.

However, they began life as rudimentary tools for growing exotic plants in otherwise inhospitable climes.

In the Roman times, Pliny the Elder reports, vegetable beds were mounted on wheels. In hot weather, they were moved out into the sun, and in winter, withdrawn under stone-glazed frames. None other than Emperor Tiberius Caesar was a big fan of the cucumbers and melons grown in this way.

This technology existed in Roman Britain – but conservatory buildings only started to be built in the 16th century.

At this time, traders were bringing lemons and oranges to Britain for the first time. They were highly prized as status symbols – as well as for their flavour and purported health benefits.

Britons faced a challenge, though. How could you grow these zesty additions to your fruit bowl in cold, drizzly Britain?

The answer was to build special-purpose buildings that would shield the delicate plants from bad weather. These were known as "orangeries" and were typically made out of wood, brick or stone with big, south-facing windows.

Right from the start, these Renaissance conservatories were used to entertain as well as grow plants – and, like today, were a way of demonstrating wealth and taste.

18th century

The story of conservatories is bound up with technological advances. In the 18th century, a Dutch scientist found that sloping glass brought in more light than tall picture windows. Today, what would a conservatory be without a sloping roof?

At around the same time, conservatories became outbuildings in the country homes of the upper classes.

19th century

The 19th century was the undisputed golden age of conservatories. There was a mania for gardening, with exotic plants arriving from all over the globe. At the same time, advances in glass manufacture gave rise to the classic iron-and-glass look.

This was also the age of large greenhouses and glass structures – at Kew Gardens, Crystal Palace and the Great Conservatory at Chatsworth, to take just three examples.

The Great Conservatory was a symbol of Victorian imperial splendour. Queen Victoria herself described it as "the most stupendous and extraordinary creation imaginable". It was a huge, tent-shaped construction that cost over £30,000 to build and required eight boilers and seven miles of iron piping to heat.

These fantastical constructions gave a huge boost to the glasshouse and conservatory industries. Consumers began to buy off-the-shelf models from manufacturers like Gray, Ormson and Brown, Foster and Pearson, J. Weeks, Boulton and Paul, and Messenger & Co.

20th century

The early 1900s saw the introduction of roof glazing. This was partly in response to the arrival of pineapples from South America and grapes from the Mediterranean.

The question was the same one asked by engineers in the 16th century: how can we maximise heat and light to grow these exotic plants?

Heating also came on in leaps and bounds, with hot air flues, steam and piped hot water providing an early version of central heating. This made conservatories warmer and more humid than ever before.

However, conservatory fever started to die down with the destruction of the First World War and the following economic depression. People simply had less money to spend. Garden staff got the sack and many conservatories were scrapped to cut costs.

Even the Great Conservatory was demolished in 1920. The golden age of conservatories was over.

The 1970s

Things took a turn in the 1970s when architects and builders started to revisit the classic Victorian look. Now, however, they were able to build conservatories using insulated glass.

Today's conservatories use aluminium, uPVC and timber as well as energy-efficient glass and other technological advances. Glazing can now be impregnated with argon for better thermal efficiency or "self-tinting" to store up heat for the evening. Conservatories can now be fitted with patio or even bi-folding doors.

Despite these changes, however, the Victorian conservatory is still the model. Think of a conservatory and you'll probably picture an ornate structure that mimics the iron-framed extensions of yore.

Perhaps the biggest difference is how they're used. Today, the greenhouse is where you grow your exotic plants and the conservatory is where you relax. This would be news to the Victorians, who would frequently entertain in their conservatories.

In fiction and art , indeed, "the conservatory often features as a place for conversations about marriage and affairs of the heart". Take James Tissot's 1875 painting In the Conservatory , "where there appears to be some unchaperoned flirting going on amongst the lush palm trees".

But however they're used, conservatories remain an elegant addition to any home.

8 benefits of bi-fold doors

Mon, 11 Dec 2023 09:00:03 GMT

Want to give your home the wow factor? Why not consider fitting bi-fold doors? Explore the benefits in our 8-point guide.

We've been opening our houses to the garden for years, often with patio doors or French doors. But is there an alternative?

Whether you're finishing an extension or looking to enhance your home's functionality without making major changes to its structure, bi-fold doors are a beautiful way to let the outside in.

These modern marvels create a seamless transition between house and garden. They provide your home with an all-important wow factor and – potentially – add value to your property.

(Though when your home looks this beautiful, you may never want to move again…)

What are bi-fold doors?

Bi-fold doors are comprised of multiple separate door panels laid out on a track system.

When opened, the panes fold outward to stack neatly on top of one another in a concertina pattern. Each panel slides and folds over the next before resting at the side of the door frame, creating an entirely open exit into your garden.

This clever design means they create a lot of space while only occupying a small area.

Bi-fold doors are easy to install – and you can have as many sections as necessary to cover the opening (between two and seven panes).

Are they just for outside access?

No. Bi-fold doors can also be fitted inside your home, creating a divide between two rooms or expanding it into one large space when needed.

Still not sold on the benefits of bi-folds? Here are eight more perks to consider.

1. They flood the room with light

It stands to reason that the larger the window, the more light can enter your home.

Bi-fold doors offer the ultimate in this regard. They stretch from floor to ceiling and wall to wall, allowing the maximum light possible while protecting you from the elements when necessary.

2. They're beautiful

Bi-fold doors bring a modern, open-plan aesthetic to your living space. They're gorgeous – and, better yet, they're customisable.

At Calder Windows, we currently offer bi-fold doors in 11 different colours and finishes – and with a choice of white or black hardware. This allows you to match your doors to your interior design.

Search "indoor/outdoor living" on sites like Pinterest or Instagram and you'll be inspired with hundreds of ideas on how to make the most of your new outdoor "room".

Which look would work best for you? To decide, consider the aesthetic you're aiming for and the age of your house.

For classic and contemporary styles, black, white and grey work well. However, in a period property, a traditional finish such as a natural wood effect or neutral shade may work better.

3. They make things not too cold and not too hot

Once upon a time, buildings were constructed with as few windows as possible to conserve heat.

But thanks to modern technology, today's glass is energy efficient. It can even help save you money on your energy bills.

Our bi-fold doors are no exception. They're built with superior seals along the door edges to ensure they're draught and weatherproof.

On the other hand, if it's excess heat you are worried about, ask the team at Calder Windows about Uni-Blinds.

These can be integrated at the installation stage or fitted into an existing frame, giving you full control over the levels of light and shade.

4. They create a seamless transition between indoors and outdoors

One lesson learnt during the COVID-19 crisis was how our homes impact our mental health.

Forced to stay home, people discovered the joy of gardening and the great outdoors. They built summer houses, decked out their patios with bars and pizza ovens and enjoyed creating a holiday-like atmosphere. And, as a bonus, we boosted our vitamin D levels in the process.

Brits are famous for complaining about the weather – but according to the Met Office, there are more than 1,300 sunshine hours in a year in the UK.

How do we make the most of those hours?

Bi-fold doors are one way to steal a little more sunshine. They're famous, after all, for creating a seamless transition between indoors and outdoors.

You can even enhance the effect with a matching floor. Many flooring companies offer choices that blur the lines from one area to the other, creating a beautiful, sleek and contemporary aesthetic.

A curated outdoor seating and dining area creates, in effect, another room. These garden spaces are ideal for relaxing as a family or as an entertainment area for barbecues and parties.

5. They're space-saving

Bi-fold doors often span the full length of a room. However, thanks to their concertina design, they actually take up very little space, opening up an uncluttered wall-length view of your garden.

At Calder Windows, we offer 17 possible configurations, available with inward and outward opening doors. A discussion with our team will pinpoint the design that works best for you.

6. They're easy to open

Despite their size, bi-fold doors are easy to open as they are designed to glide along their track.

Our doors have built-in four-rail aluminium roller tracks, allowing smooth and effortless movement.

7. They're secure

From a security point of view, the rear of a house is the most vulnerable. However, with the right measures and precautions, bi-fold doors can be one of the most secure options.

Our bi-fold doors feature multi-point locking systems, making them more secure than a standard door.

And that's not all. They're also supplied with toughened glass, a high-security Yale lock and an anti-jarring pin enclosed within the roller track. This means the door can't be removed from the outside.

8. They're easy to look after

Despite the expanse of glass, bi-fold doors are easy to keep clean – and with a yearly service to lubricate the locks and wipe down the frames, they'll stay in peak condition.

Calder Windows' bi-fold doors have unique D-shaped interior handles with an intelligent anti-mishandling feature that stops the shoot bolt from scraping the floor. This helps to protect the bolts from damage.

Calder Windows is an experienced bi-fold door supplier based in Wakefield, West Yorkshire.

If you want quality at an affordable price, give our team a call today . Or why not pop into our showroom to see our huge range of colours and designs? We'd be happy to discuss which bi-fold door configuration is best suited to your home.

Which home improvements make the best investments?

Mon, 04 Dec 2023 08:47:58 GMT

Plans to renovate? Find out which home improvements will bring the best return on your investment.

Home improvements are a great way to add value to your home. Investing a little time and money in different areas now can mean not only creating a nicer living space but also adding a sizeable amount of value to your property.

But where to start? When considering a revamp, the possibilities can seem endless. Is it time for a bathroom overhaul or do you start with those draughty windows you've been meaning to get around to? And which one will add the greatest value when you eventually sell?

While you contemplate where exactly to invest your money, it's important to remember that not all renovations are created equally.

Fortunately, at Calder Windows we have more than 30 years of home-improvement experience under our belts – so we know a thing or two about upgrading your living space.

So, we've done the hard work for you. Save yourself the uncertainty and take a look at our list of home improvements that will bring you big returns on your investment (ROI).

Adding a conservatory or sunroom

One of the most effective ways you can boost your property's value is to add a conservatory or sunroom.

Although a slightly bigger undertaking than a lick of paint, a conservatory on your property can net a whopping 108% ROI .

Not only will you reap the rewards of your investment when your home is on the market, but a conservatory or sunroom can also greatly improve your quality of living while you still call the place home.

A whole extra living space in the house? A beautiful view of your garden? Shedloads of natural light? If you've got the cash and the time, it's a no-brainer.

Upgrading windows

New windows have to be one of the smartest ways to boost your property's perceived and actual market value.

While shiny, neat, new windows can give your home the edge in terms of kerb appeal, they are also an investment that gives back – estimates put their ROI at around 70% .

But the benefits don't stop there. Replacing old, leaky windows with superior ones can also go hand-in-hand with lower energy bills and a healthier, draughtless, damp-free living environment.

No question: window replacements are very much a long-term home improvement.

Replacing an old front door

If you're looking for a quick and easy home improvement with a big return on your investment then look no further. Adding a new front door to your property has shown to have an impressive average ROI of 101% .

A smart new front door helps any property create a great first impression. Not only that but investing in a quality product – like a composite door – can improve your home's security and keep out more of that annoying traffic noise.

Replacing your front door is a sound and straightforward investment for your home. With the help of a trusted supplier and installer , the most trouble you'll have to go through is choosing a style that you like.

Investing in a loft conversion

If you're looking for a slightly bigger undertaking then why not consider a loft conversion? Fitting out your attic has the potential to increase your property's value by up to 20% .

While the initial expenditure of this larger-scale project may be higher, the impact it has on prospective buyers means that you should be able to recoup these costs (and then some) when your property is on the market.

Not to mention the benefits for you until that time.

With some good insulation and the right windows , a loft conversion can add heaps of square footage to your home and even help you save on your heating costs (bonus).

Revamping your garage

With driveways now a lot more commonplace and roadside parking aplenty, many homeowners are looking to transform their lesser-used garage spaces into additional living spaces.

And it seems to be a renovation that pays off. Prospective buyers are so drawn to the extra space, in fact, that a well-done garage conversion could potentially increase the value of your property by up to 15% .

Flood the space with natural light and you have a blank canvas to create a whole new living area. Perhaps it could be an office, a family room or even a studio apartment.

Landscaping your garden

Just like your home, your garden can have a big impact on value. One of the more hands-on ways you can give your property the edge is by creating a lovingly landscaped green space.

Something as simple as a tidy-up will leave a good impression on future buyers. However, you could also consider creating a seating area for socialising or plenty of open grass for kids – all plus points for when you're hoping to sell. You could even weather-proof your garden with a small studio or summerhouse.

Create a space where you and your family can spend lazy, sunny days for an ROI of up to 88%.

What to consider before renovating

It's important to remember that the return you can expect to see from your home improvements is dependent on the quality of work carried out.

Cutting corners with sub-standard suppliers or fittings now will likely prove to be costly in the long run. Choose a company you can trust – one with plenty of experience behind it and reliably good customer reviews.

Skylights vs roof lights vs loft windows: what's the difference?

Mon, 13 Nov 2023 09:00:03 GMT

Roof lights, skylights, loft windows… aren't they all the same thing? Not quite. Learn the key differences in our homeowners' guide.

Skylights. Roof lights. Loft windows. They're all popular options for homeowners who want to shower their living space with natural light.

This is nothing to sniff at. There are many benefits to natural light in the home, from boosting productivity and well-being to saving cash on those ever-growing energy bills.

But which of the three options should you choose? Aren't they all the same, anyway? They're all big pieces of glass that sit within the roof, after all.

That is true, for the most part. But there are subtle differences in terminology – and not-so-subtle differences in regulation – that are worth paying attention to.

Here at Calder Windows, we've been supplying and installing roof-mounted glazing for decades. We're here to help you make sense of the three options and choose the one that best suits your needs.

Skylights vs roof lights

OK, first things first: semantics.

Skylights and roof lights are essentially the same thing. They're glazed openings that are fixed in the roof and permit natural light to enter a room.

Some window manufacturers and suppliers use the terms to describe different kinds of products – but the distinction is murky and tends to be manufacturer-specific. Others use the terms interchangeably.

Local habits play a part too. People in the States tend to use the term "skylight" more often, while British English speakers err towards "roof light". You say "tomato", et cetera et cetera.

If the definition of "skylight" or "roof light" sounds very much like the definition of "a window", then – yes, it's not far off.

But it's not quite as simple as "a skylight is a roof light is a loft window". Loft windows are the odd one out. Here's why.

Loft windows

Skylights and roof lights are, more often than not, fixed panes of glass that sit within the roof. They can't be opened – or, if they can, they only open a teensy bit to allow some ventilation.

Loft windows are, well, windows. They come with all the features you'd expect from a window. They're hinged at the top and can open fully, just like any other window. Under certain circumstances, they can even be classified as emergency exits.

Thanks to their window-ness, loft windows are covered under BS EN 14351-1:2010. This is the British Standard for all non-fire-resistant windows and doors.

So loft windows have more features than skylights – but because they're governed by regulations, you have a little less flexibility in terms of where you can install them.

Skylights are typically installed on flat roofs – and are often out of plane (jutting out) from the level of the tiling.

Loft windows, on the other hand, must be installed in-plane (level) with the surrounding roof at a minimum pitch of 15 degrees.

There are other stipulations too. For instance, loft window manufacturers must test their products to ensure they perform adequately in different weather conditions.

Benefits of roof-mounted glazing

So, what's the big deal with roof-mounted glazing. you ask?

There are three main benefits to consider. The first is energy efficiency.

This might sound counter-intuitive. Surely a roof-mounted window is less insulating than, well… a roof?

Yes and no. Modern roof windows are almost always double- or triple-glazed. They're specially designed to trap heat and be impervious to moisture or leaks.

And there are other energy-efficiency gains. For one, roof glazing allows natural light to flow into the room. This means you're less likely to run up your energy bill by leaving lights on.

They don't just bask the room in sunlight, either. They also allow that lovely summer heat to come in and warm your living environment.

We've already covered the second benefit – sort of. Roof glazing means more light in your living space – and more light is good for the soul.

This isn't us getting philosophical. Scientists have studied the benefits of natural light – and have concluded that exposure to sunlight supports our natural sleep rhythms and, by extension, improves overall well-being.

Finally, there are the aesthetic benefits. Roof glazing is gorgeous to look at and can even improve the value of your home. How's that for an investment opportunity?

Another option: roof lanterns

If a skylight, roof light or loft window doesn't cut the mustard for you, then maybe you're on the lookout for something with a bit more pizazz?

Look no further than the roof lantern. These show-stopping glass structures sit on flat roofs and are made up of several panes of glass to create a pyramid, box or dome-like shape.

Unlike the other three options, roof lanterns typically protrude quite far from the roof. This means they offer maximum exposure to natural light.

Not only are they fantastic at letting the light pour in but they can also make your living space appear more spacious.

Interested in roof glazing?

Luckily for you, we can offer all of the above.

Calder Windows is one of Yorkshire's most trusted specialists in doors and windows. With a huge range of customisable skylights and roof lights available, we guarantee we can help create the perfect look for your home.

How to find a window installer you can trust

Fri, 10 Nov 2023 09:00:00 GMT

In a sea of choices, how do you find a reliable window installer you can trust? Learn how to avoid cowboy companies and find one that genuinely cares.

You’re ready to make the next step in your home improvements.

Is it a new door, new windows, new conservatory or all three?

Big decisions, for sure. But there's a bigger one to come: which door or window firm will you choose to do the job?

The internet and local directories helpfully list many companies – but before you part with your hard-earned money, you want peace of mind that you're making the best choice.

We've all heard the horror stories!

So, how do you avoid being a victim of scammers and, instead, find a window installer you can trust?

You want a good return for your investment, high quality, improved kerb appeal for your home, good energy efficiency, security and a design that is tailored to you.

Ticking all these boxes is no small feat. But if you follow our tips, you should have no trouble finding a firm that goes above and beyond.

Research the company's history

Take the time to research the company.

What is their history?

How long have they been in business?

The company's history is a powerful tool for establishing credibility and reliability. Years of experience produce a culture of teamwork among the staff and pride in their work.

A company that has successfully weathered the storm in times of recession shows resilience, stability and a willingness to progress with new technologies.

And a related question: is it a family-run business?

This is often a sign of a committed and unified leadership, which has built the business to pass on to the next generation. This all adds up to a brand you can trust.

Check reviews and ratings online

Why do we check reviews?

Because reviews build credibility. They offer an outlet for real customers to provide helpful feedback on a service or product – and, in turn, greatly enhance customer trust.

Don't just look at the star rating. Read the in-depth reviews to see what customers appreciated most.

Was it the professional, friendly service? The quality of the product? How they dealt with potential problems? A well-rounded review will cover all these topics and give you a good overall view of the company ethos.

Make sure they're FENSA-approved

FENSA is a government-authorised scheme that regulates the window and door supply industry in the UK. It is a certificate of quality proving regulatory compliance within the law.

Since 2002, it is actually illegal to install double glazing without adhering to building regulations. This includes replacement of windows, doors, roof windows and roof lights in England and Wales. (Just replacing glass in an existing frame is exempt.)

You can only get a FENSA certificate from a FENSA-approved installer. It's a guarantee your installation complies with building regulations, is registered with the local council and is backed by guarantee insurance.

The FENSA website can help you find an approved installer in your area.

Look for qualifications

What qualifications do the installers have?

Are the staff qualified to an appropriate NVQ level?

Those working as glaziers, installing glass into frames and maintaining glazing installations (usually windows and doors) need a minimum of an NVQ level 2 in glazing.

For more experienced glaziers, you can expect an NVQ level 3 – along with further training in dealing with various recurring issues. This includes working with glazing installations that have complex requirements, such as the identification and rectification of technical problems.

In addition, there are qualifications for those who install replacement glass, supporting frames and units.

Similar NVQ qualifications are needed in the role of window (fenestration) surveying.

Ask for a guarantee

What guarantees does the installer offer?

While a FENSA certificate proves quality of workmanship and legal requirements, you'll want to know that the installer itself is confident in its workmanship and materials. A guarantee is a surefire signal of this.

Do they offer a quality-assured framework, ensuring all products are of a consistently high standard? Do they offer a warranty? How long is it? Does it match the standard length for a home improvement guarantee of 10 years?

Customer service on first contact

What are your first impressions?

In any customer-based industry, first impressions go a long way. Being able to visit a showroom allows you to view the products up close, assess the quality and ease of use, and explore finishes, colours, materials and designs.

Discussing your personal needs with an experienced member of staff will help you make a choice that's specifically tailored to you and your taste. They should also help answer questions on practical aspects, such as energy efficiency and security.

You want to feel relaxed and assured throughout this first meeting. If they can't answer your questions and hit you with a hard sell instead, we advise that you run for the hills.

Ways to find trusted suppliers

A good starting point is to ask family, friends and neighbours for recommendations. There's no better recommendation than a personal recommendation, after all.

Failing that, look online. Use search engines or online directories such as yell.com . Browse each company's website and social media accounts to see testimonials and examples of projects they've worked on in your area.

You can also check reviews on independent sites such as www.checkatrade.com for verified customer feedback.

When you enter into conversations, don't be afraid to ask questions. A reputable company will be happy to provide evidence of its experience and qualifications, official trade body membership and examples of previous work.

Its quote should be upfront about all costs involved. This includes things such as scaffolding (if needed), removal and disposal of old doors and windows, and repairing any plaster around the new windows.

Calder Windows is a family-run business that has provided window fitting services for over 30 years – with more than 100 years of combined expertise in our team.

Should I choose a conservatory or an orangery?

Mon, 06 Nov 2023 08:52:37 GMT

What's the difference between a conservatory and an orangery? Let's explore what makes these extensions uniquely different – and the benefits of each.

So, you'd like to add an extension to your home but don't know how to choose between a conservatory or an orangery.

It can feel a bit like comparing apples to apples. (Or, erm, orangeries to orangeries.)

Often, but not always, constructed as home extensions, these structures are built from glass and brick. They're usually designed for snoozing away a beautiful summer afternoon. Somewhere to grow your own tropical jungle, perhaps – or just hide the washing.

However, there are a few key differences to consider.

Visual differences

The quickest way to determine if an extension is an orangery or a conservatory is to look at the roof and the ratio of glass to brickwork.

Conservatories are predominantly glass with a brick base. Orangeries, meanwhile, are the opposite – these have very large windows embedded within brick walls.

A flat roof with a glass lantern signifies an orangery, whilst a pitched or slanted roof made of glass labels it a conservatory.

Both options make a great visual addition to your home, so the choice largely comes down to personal preference and how exactly you'd like to utilise the extra space.

That's why it's important to understand what each extension offers – and what paperwork you might have to contend with.

Planning permission for different extension types

The important bit.

Typically, neither an orangery nor a conservatory needs planning permission as they are considered single-story extensions.

That said, there are exclusions. If you live in a listed building or conservation area, you're likely to need planning permission. There are rules around around roof heights and positioning too, which everybody should pay attention to.

Lawful development certificates are recommended as they provide proof that the build was legal before starting.

In any case, it's best to do personal research or consult an expert before embarking on the journey.

Cost differences

Prices are hugely dependent on size, materials and installation costs. But as a rule of thumb, you can expect an orangery to be about twice the price of a conservatory.

A higher price tag shouldn't put you off by default, however. Orangeries generally offer more functionality and a bigger increase in property value.

Material differences

The difference in cost between conservatories and orangeries can largely be attributed to two things: materials and installation.

Conservatories are traditionally built from three materials: uPVC, aluminium or timber.

uPVC is popular because it's sturdy, affordable and easy to work with. Its entry-level price point and quick construction make it a popular choice for UK households.

Love the classic look? You might want to choose timber. However, it costs more than uPVC and is likely to incur higher labour costs too. And unlike uPVC, it's not weatherproof, so will need to be managed to prevent draughts in the long term.

Aluminium frames come with higher price tags but are the most robust of the three materials. Aluminium is on par with uPVC for heat retention and isn't prone to degradation or warping like wood.

Unlike wood, however, which can be treated to extend life expectancy and will perform well when properly cared for, aluminium frames can be tricky to repair in the unlikely event that they're damaged.

Orangeries are much simpler. They tend to be made from insulated brickwork and glass, so the customisation options stem from finishes. You'll also have to make decisions about how energy-efficient the windows, doors and flooring should be.

Orangeries are more efficient…

On that note, orangeries are generally more efficient than their glass-clad cousins.

Structurally, they're more robust than conservatories – and the greater ratio of brick to glass means they retain more heat for longer.

Adding roof vents allows for better climate control and prevents overheating, so the space can be kept at an optimum temperature all year round.

…but conservatories offer more natural light

If light level is the single most important decision-making factor, conservatories are the top choice. The mostly glass construction of the walls and roofs permits more light.

Orangeries are also very light and airy, but a more substantial roof means you're sacrificing some light in return for a beautiful design.

Design differences

Orangeries typically offer more flexibility in terms of space, size and layout. This makes them ideal for kitchen extensions or freestanding outbuildings.

The most popular style for a conservatory is as an annexe – but it's worth understanding the Victorian, Edwardian and Georgian conservatory designs to find the one that best complements your home's character.

Which came first, the conservatory or the orangery?

Orangeries are the great-grandfathers of the modern conservatory. They date back to the 17th century when glass-making advances in Renaissance Italy led to a boom in popularity for large, clear panes of glass.

Adding huge windows to extensions granted plenty of light and made the structures ideal warm environments to house exotic plants. Soon, orangeries became a status symbol for wealthy owners of grand homes and estates.

The original 17th-century orangery typically had a solid flat roof. However, by the 19th century, the architecture had evolved to include pitched glass panelling (the iconic lantern element) to maximise light.

So, which should you choose?

Ultimately, choosing between a conservatory and an orangery is going to come down to what is right for you. It all depends on your space, your vision and your budget.

The good news is that budget isn't everything. Sure – orangeries might offer better energy efficiency for a higher upfront cost, but there are plenty of options for tighter budgets too.

For instance, here at Calder Windows, we offer warm roof conservatories from Supalite and Equinox. These are designed to keep heat trapped inside, so your conservatory will stay warm in winter and delightfully cool in summer.

What are composite doors made of? (And how do they work?)

Fri, 03 Nov 2023 07:09:37 GMT

Composite doors are popular for their style, strength and functionality. But what, exactly, goes into a composite door? Find out in our quick guide.

Composite doors are a modern and popular choice for homeowners who are looking to enhance the appeal and aesthetics of their homes.

These doors make for a versatile alternative to traditional wooden or uPVC doors and offer a wide range of benefits, including better security and durability.

But what are composite doors actually made of? Is it just plastic? And what's so special about them, anyway?

What are composite doors?

Composite doors are a modern alternative to traditional doors. They come in a variety of colours and materials, which often combine to mimic the grain of a wooden door.

This type of door is very popular nowadays. There are several reasons for this – for instance, composite doors can enhance the appearance of a property, lower maintenance levels and add an extra level of security .

What are composite doors made of?

Let's nix the common myth right away: composite doors are not just made from plastic. In fact, they're composed of various different materials.

The clue's in the name. The word " composite " is defined as "made up of several parts or materials". When it comes to composite doors, that definition is right on the money.

The core of a composite door is typically made of solid timber or a solid foam-filled structure. This core is surrounded by a layer of reinforced thermosetting resins.

Finally, the outer layer is usually a high-density "skin". This mimics the appearance of wood but is much more resistant to the elements and requires minimal maintenance.

These materials combine to create a door that's greater than the sum of its parts. For example, while the core provides strength and insulation, the resin middle layer enhances the door's robustness and weather resistance.

Different materials bring different benefits, too. For instance, you might choose a foam core if you're aiming for a lightweight result.

Composite doors are very customisable, too. Here at Calder Windows, we offer a wide variety of custom windows ranging from understated to flamboyant. This means you can give your composite door a truly personal touch.

What's the difference between uPVC and composite doors?

Composite doors and uPVC doors look similar and are both popular choices for homeowners. However, they have some very distinctive differences.

While composite doors are made of, well, a composite of materials, uPVC doors are made entirely of unplasticised polyvinyl chloride.

We won't get into the science here. The short version is that uPVC doors are easy to maintain but are not as sturdy as composite doors.

However, uPVC doors are more budget-friendly and affordable due to the materials used to make them. Either way, here at Calder Windows, we're happy to supply and fit whichever you choose.

What are some of the benefits of composite doors?

There are many benefits to composite doors . In fact, you may well wonder, "Where have these doors been all my life?"

For a start, composite doors are highly durable and weatherproof – but without looking like a concrete slab on your front porch! They're specially made to endure harsh weather conditions, including rain, wind and extreme temperatures without degrading or warping.

These sturdy doors also enhance soundproofing due to the dense materials used. This also makes them more resistant to wear and tear. In the long run, they could save you money as they won't need replacing as often.

Are composite doors environmentally friendly?

We all want to help the environment in whatever way we can. But can composite doors help to shrink your carbon footprint?

From an energy-efficiency point of view, the answer is a resounding "yes!" See, composite doors are designed to trap heat in your home, which means you're less likely to keep the heating on full blast during winter.

Of course, this is good for your wallet – but it's good for the planet too.

Do composite doors look good?

If all these benefits aren't enough to convince you to invest in composite doors, then consider the "wow" factor.

You can choose the type of wood grain, the colour and even the windows and styles, so you'll have a door that's completely unique and stands out in the street. On older properties, they can modernise the house, and on new properties, they can add a beautiful and classic twist.

These doors are perfect for the conscientious homeowner who's looking for a high-class and reliable door to enhance the look of their home.

Are composite doors secure?

Sadly, we live in a high-crime world, so safety is a must. Can composite doors help deter those pesky burglars?

Yes. Because our composite doors are very sturdy, they make it difficult for intruders to gain entry. And even if you opt for doors with windows, they won't be flimsy single-paned glass but sturdy laminated or toughened glass.

Our composite doors also come with multi-point locking systems. Quite simply, this means the door locks at several different points once the key is turned. This makes entry even more difficult.

Where can I buy composite doors?

If you live in Yorkshire, you're in luck.

At Calder Windows, we've been supplying and fitting composite doors in Yorkshire for decades. We know the industry like nobody else – and we've built a reputation for quality workmanship, great service and very competitive pricing.

If you need composite doors fitted by a trusted and reputable supplier, don't hesitate to get in touch for a no-obligation quote.

How to prepare your conservatory for winter

Fri, 13 Oct 2023 08:00:01 GMT

Does your conservatory turn into a refrigerator as soon as there's a cold snap? Learn how to turn that summer room into a cosy, all-weather haven.

As winter approaches, we can look forward to crisp, cool afternoons under blue skies and enjoy the snow gently falling in our back gardens.

And where better to enjoy the views than from your conservatory ? It's the perfect place to snuggle up and watch winter work its magic.

Or maybe not. If your conservatory feels like more of a fridge than a cosy oasis, then you'd probably rather stick to the living room instead.

But it doesn't have to be this way. With a little preparation and a few adjustments, you can turn that cold extension into a warm winter haven.

We've come up with some quick fixes and long-term changes to help you prepare your conservatory for the cold weather. All will make a difference, so you can choose the tips that make the most sense for your needs and budget.

First things first

Before you try any hacks or tips, make sure to give your conservatory a good clean and check for any damage. Look for things like leaks, cracked glass or damaged seals. All these can affect your conservatory's ability to retain heat, so might be the cause of the chill.

Now seal any gaps or cracks. You can do it yourself (with a little research) or call in a professional to do it.

Choose warmer colours

One of the cheapest ways to make your conservatory a more inviting place to be is to work on the décor. Perhaps part of the problem is that it simply looks cold.

By painting your conservatory warmer colours, you can transform the space into a place the whole family will love to spend time in.

And it may sound silly, but lighting will make a difference! Use warm bulbs and lighting fixtures to enhance the ambience. You could use string lights, floor lamps, LEDs or candles. These will also add to the festive cheer of the season.

Make it a snuggly haven

There's something magical about snuggling up in a conservatory, listening to the rain patter softly against the glass.

So, why not try adding some cosy cushions and blankets to snuggle up in and create a warm atmosphere?

Stock up on winter essentials too. Water bottles, warm drinks and other creature comforts should be readily available to ensure you fully enjoy and relax in your space.

Consider thermal mass

"Thermal mass" is the ability of a material to absorb and retain heat.

Things like heavy furniture and stone flooring have a high thermal mass and can contribute to a warmer, more stable temperature. So, maybe it's time to rearrange some furniture for winter!

On the other hand, if you're having trouble with cold floors, you could add some warm, thick rugs. These can help keep your feet warm and prevent draughts from the floor.

Upgrade your curtains or blinds

Believe it or not, blinds and curtains can really contribute to household insulation. So, buying special thermal blinds or shutters can add an extra layer of protection from the cold. This will be especially noticeable on those harsh winter nights.

Invest in heating

If there are no radiators in your conservatory, you could consider getting a portable heater as a quick fix or installing some fixed radiators to warm you up.

Of course, living costs are increasing constantly. So if you do install new radiators, try to plump for an energy-efficient model to keep costs low. And if you haven't got one already, then maybe consider installing a smart heating system that maintains a constant temperature to ensure optimum comfort.

If cold floors are keeping you awake at night, you could also consider underfloor heating. Although it's often considered expensive to run, the reality is that both the installation and running costs can work out cheaper than you might think.

Insulate any cavity walls

If your conservatory has a dwarf wall (a short brick construction around the base), make sure it's insulated. Installing high-quality insulation can significantly impact the thermal efficiency of the space.

Install insulated conservatory roof panels

Insulated roof panels can help to maintain a more constant indoor temperature and reduce heat loss or gain. This means a warmer conservatory and – hopefully – cheaper energy bills to boot.

We recommend the SupaLite conservatory roofing system . This not only effectively traps heat, but it also looks great and is built to last for many years. Plus, if you choose Calder Windows for your conservatory roof installation, you'll enjoy a 10-year warranty as standard.

Double or triple glazing

Another great option to transform your conservatory is to replace your single-glazed windows and doors with double or triple glazing.

This long-term solution improves insulation, minimises heat transfer and contributes to energy efficiency, helping to save you money in the long term.

Learn more about our unique, extra-secure triple-glazing system .

Secondary glazing

If replacing your windows or conservatory panels isn't feasible, then you may want to look into secondary glazing. This involves adding an extra pane of glass to existing windows, providing extra insulation.

Conservatory experts for 30+ years

At Calder Windows, we have more than 30 years of experience in installing windows, doors and conservatory products. That includes energy-efficient solutions such as thermal conservatory roofs , as well as double and triple glazing .

Should I choose aluminium or uPVC windows?

Mon, 09 Oct 2023 08:00:02 GMT

There are many types of windows on the market, but two of the most popular are aluminium and uPVC. Learn the pros and cons of each in our guide.

Choosing windows is not as easy as it seems.

From varying designs to different colours and textures, there's plenty to consider. And that's before we get into the nitty-gritty of the material they're made of.

Two of the most popular materials for windows are aluminium and uPVC . Both have benefits aplenty – but which option is best for you?

Let's have a good look at their pros and cons. This way, you'll have all the information you need to make the right choice for your home.

Aluminium windows: the pros

1. Long lifespan

Aluminium replacement windows make for a great investment because, in the long term, you're going to get your money's worth. Aluminium windows have a lifespan of anything from 30 years upwards, meaning replacements will be a long way off.

2. Durable

The reason these windows have such a long lifespan is that aluminium is a very durable metal. Even extreme UK weather can't shake them!

3. Lightweight and versatile

Aluminium is a very lightweight material. This makes it extremely versatile as it can be used for things like large statement windows and skylights.

As the profile of the window tends to be thinner due to the material, it also allows a little more natural light to flow through your home.

4. Low maintenance

If maintenance isn't your strong suit, aluminium windows are the right option for you. Unlike wooden frames, aluminium needs very little maintenance. A quick rinse while you clean your windows is all they need to stay in tip-top condition.

5. Recyclable

Another little bonus with aluminium windows is that they're 100% recyclable. When they reach the end of their lifespan, the old frames can be melted down and used for something else. Perfect!

Aluminium windows: the cons

The only real disadvantage of aluminium windows is their cost. Aluminium windows usually cost a little more than their uPVC equivalents.

This is due to various factors. The material, its durability and the lifespan of the windows all contribute to the price. In short, you're getting a longer-lasting product so you have to pay a little more.

uPVC windows: the pros

1. Energy efficient

uPVC windows are known for their energy efficiency. They're highly effective insulators and can help regulate the temperature inside buildings all year round. This type of window can help reduce the heating costs – especially if they're fitted with double or triple glazing.

2. Affordable

There's no two ways about it. Out of uPVC and aluminium, uPVC comes out on top in terms of pricing. If you're working on a tight budget, these windows are the preferred choice as they allow you to upgrade your home without breaking the bank.

3. Durable

Both aluminium and uPVC are man-made materials that don't expand or contract. This means they won't warp or crack in the same way as other materials and can be easily maintained with some light cleaning.

4. Long lifespan

Like their aluminium counterparts, high-quality uPVC windows will last for years with proper care. You can expect to get 20 to 25 years of use from a uPVC window before it needs replacing.

uPVC windows: the cons

Similarly to aluminium, the disadvantages of uPVC windows are very limited. Nonetheless, we will run through some of the standout issues.

First, uPVC isn't quite as durable as aluminium. This means that uPVC windows are more susceptible to damage as the material can be more easily marked, dented or cracked. However, they're still very robust and can withstand a significant amount in terms of weather and regular wear and tear.

uPVC has excellent insulating properties which can result in dirt and debris clinging to the windowsills and frames. Unfortunately, this means they may require a little more cleaning than the aluminium counterpart. However, if you're not shy with a bucket and sponge, this won't be an issue.

A word on style

We haven't considered style an advantage or disadvantage, because, ultimately, it comes down to personal taste.

Some consider aluminium windows to be a little more stylish because they tend to have slim frames. This gives them a crisp, modern look with a slight industrial flavour.

uPVC windows, on the other hand, have a more "typical" look that's arguably more versatile.

Again, it's a question of taste. But you can think of it like this: if you want to stand out, choose aluminium. If you just want some classic-looking windows, uPVC will do just fine.

The bottom line

Overall, uPVC and aluminium are fantastic options to consider when choosing to upgrade your home. Both are available in a range of colours, shapes and sizes and can be supplied and fitted by us across West Yorkshire.

So, if you're stuck between the two and our list of pros and cons hasn't done enough to sway you one way or another, give us a call and our friendly team can help you choose the right option.

Do your windows need an upgrade? Or maybe you're in the market for something a little different? With a huge selection of colours and styles, Calder Windows has something to suit everyone's needs. And with over 30 years of experience, we know how to make your vision a reality.

Why windows matter: the health benefits of natural light

Fri, 06 Oct 2023 08:00:00 GMT

Windows aren't just functional – they also let in natural light, which has a range of health benefits. Find out why windows matter in our article.

Windows are more than just aesthetically pleasing. They can actually have health benefits too. Don't believe us? Let's take a look…

It's often said that eyes are the windows to the soul. If you want to know if someone is upset, lying or angry, you can sometimes tell by looking at their eyes.

But if eyes are the windows to the soul, what if our soul is feeling a bit low? Could windows themselves hold the key?

Light: nature's doctor

If you're online or on the high street shopping for windows, you're probably asking yourself questions like: what colour should the frame be? Do I want double or triple glazing ? How about frosted glass?

But the thing is that windows are more than just a face-lift for your home. They also fill it with light – and light in the home can improve your health and lift your mood. Truly, they're the unsung heroes of our homes .

Windows are a gateway to Mother Nature's wellness centre. When natural light flows into our living spaces it can boost our happiness and make us more productive. Just think about starting the day in the dark of winter as opposed to a bright summer morning. Why is it that the one can be so much more enjoyable than the other?

It's not just mood-altering – it's also vital for the production of vitamin D. When your skin is exposed to ultraviolet B (UVB) rays from sunlight, it initiates a chemical reaction in the skin. UVB rays have just the right amount of energy to form vitamin D in our bodies.

Vitamin D is essential for several bodily functions and for maintaining strong bones and teeth. It also plays a role in our immune systems, cell growth and neuromuscular function.

Now it's important to note here that UVB rays are usually blocked by ordinary glass windows. If you're behind glass, you won't receive the necessary UVB exposure for vitamin D synthesis. So when the sun's shining, throw those windows wide to let the UVB rays in.

Bi-folding doors can also be an excellent way to allow oodles of precious rays into your home.

But what if it's freezing outside and the very thought of opening the windows gives you a shiver? Well, natural light can have a significant impact on our mental health, even if it is coming through glass.

Exposure to natural light helps regulate our circadian rhythms, enhancing mood, sleep patterns, and overall well-being. Sunlight stimulates the production of serotonin, which is associated with happiness and reduced stress. It also prompts the release of melatonin which helps you get to sleep.

Serotonin and melatonin levels have come to the fore in recent years as more people have become aware of seasonal affective disorder (SAD). This can affect people when they get insufficient light exposure and typically strikes during the winter months as the days draw in.

While the exact causes of SAD are not fully understood, the theory is that a lack of sunlight might stop a part of the brain that produces serotonin and melatonin. Natural light is needed for your body to time various functions such as when to wake up or when to go to sleep.

Lower levels of sunlight can affect our body's natural ability to discern these times of the day. Having plenty of windows to provide that much-needed natural light all year round – but especially in winter – can really help our mood.

Is light a disinfectant?

Researchers from the University of Oregon recently demonstrated that sunlight can help kill harmful bacteria.

The researchers collected regular dust from homes and constructed an experiment which replicated natural environments in the home under glass. Remarkably, the dust which had been exposed to natural light had less than half the bacteria than the dust which had been left in darkness.

It might come as a surprise that natural sunlight is such an effective antibacterial agent because most window glass filters out UV light, the element of sunlight that's fatal to bacteria. Sunlight, then, can kill bacteria even when filtered through glass.

Can natural light boost your productivity?

Research published by Eco-Business claimed that workplaces with sufficient daylight saw an uplift of between 5 and 40% in productivity and sales. Studies in schools have similarly suggested that pupils retain information far better if regularly taught in classrooms with plenty of windows.

The playwright George Bernard Shaw went so far as to build a rotating writing shed. As the day progressed, he would rotate the hut in order to get maximum sunlight. In 1929, posed in front of his invention for Modern Mechanics and Inventions magazine, extolling the healing properties of sunlight.

Houseplants

Something else that loves the natural sunlight is your plants – and plants themselves are said to be good for you.

First, indoor plants act as natural air fresheners. Through a process called photosynthesis, they absorb carbon dioxide and release oxygen. This can enhance the air quality in your home.

Indoor plants can also have a calming and stress-reducing effect on your mental health. Research has shown that being around plants can lower stress levels, reduce anxiety and promote a sense of well-being. As any green-fingered friend will tell you, caring for plants can be both meditative and rewarding.

Finally, indoor plants can help increase the humidity levels in your home, which can be beneficial in dry climates – and can also help prevent dry skin, irritated eyes and respiratory issues.

Conclusion

Windows are so much more than functional and beautiful. They also fill your house with light – something that can be good for your mood, your health and your houseplants.

How doors and windows can help your home go green

Mon, 02 Oct 2023 17:11:08 GMT

Domestic heat loss means higher fuel bills and carbon emissions. Learn how the right doors and windows can help you save cash and go green.

The body content of your post goes here. To edit this text, click on it and delete this default text and start typing your own or paste your own from a different source.

Heat is often lost through doors and windows. This can be caused by several problems, including inadequate insulation, poor sealing and inefficient glazing .

For every degree of heat lost, your central heating system has to work that little bit harder. This means higher bills, more carbon emissions and a house that feels more like a refrigerator than a home.

Is it worth suffering in silence? No.

Many of the issues caused by heat loss can be resolved by upgrading to modern, energy-efficient doors and windows . Here are just some of the options available from Calder.

Double and triple glazing

Double- and triple-glazed windows are highly effective in limiting heat loss in a home.

They're made of multiple layers of glass with insulating spaces in between, which act as a barrier to heat transfer. The insulating layers trap warm air inside the house, preventing it from being sucked outside.

Many houses in the UK were built before the advent of double glazing. But with our cold winters, it's amazing how much difference they can make once installed.

The benefits are threefold. Double- or triple-glazed windows reduce energy bills, increase thermal comfort and help reduce your carbon footprint. They make an excellent investment towards energy-efficient and eco-friendly living in the UK.

Learn about our A++-certified triple-glazed windows and doors .

Composite Doors

Composite doors are designed with a classic timber appearance but are built to modern energy-efficiency standards. This means you don't need to compromise on style to achieve excellent insulation.

They incorporate a solid timber core, complemented by a surrounding layer of materials such as uPVC , laminate or fibreglass.

The combination of solid timber and modern materials enhances the door's overall durability, density and strength, making it a robust and headache-free option for your home. You won't need to worry about warping, creaking or leaking as you would with other traditional front doors.

Choose a composite door and you can rest easy knowing that your door is easy to maintain, looks great and is improving the energy efficiency of your home. Win-win-win!

Explore our range of attractive and robust composite doors .

Quick Fixes

Triple glazing and composite doors provide instant and impressive results. However, they take a fair bit of planning and a little investment.

In the meantime, why not consider these "quick fixes"? Both are simple and affordable ways to reduce heat loss and make your home more comfortable.

Draught excluders

Draught excluders have come a long way since the 1970s. It's not all about novelty sausage dogs and garish floral patterns anymore.

There are plenty of stylish and inexpensive options available nowadays, from door brushes to window wedges. You can even buy clip-on draught excluders that stay firmly in place even as you open and close the door.

Window dressings

Upgrading your curtains or blinds can help to trap heat and keep your home toasty and warm. Whether you opt for curtains, blinds or both, going made-to-measure can make all the difference. Made-to-measure blinds and curtains are designed to fit your windows perfectly, creating a snug and insulating barrier that helps to retain heat.

Choose your material wisely too. Thicker fabrics are good at retaining heat and reflective materials will create a thermal barrier, which helps to reflect heat back into your home.

Why choose Calder?

At Calder Windows, our products are attractive, secure and designed with energy efficiency in mind.

We supply robust, energy-efficient doors and windows that are built for British weather. And with more than 30 years of experience, we have the know-how to provide impeccable service and a fast, fuss-free installation.

In fact, we're so confident in our quality standards that all installations come with a 10-year warranty.

Are windows liquid? 8 window facts and misconceptions

Fri, 15 Sep 2023 08:00:00 GMT

Did windows used to be taxed? Can they increase the value of your property? Find out the answer to these questions and more in our five-minute read.

Everybody knows what a window is, right? Well, yes and no. Despite their ubiquity, there are still plenty of myths and misconceptions knocking around about them.

Some of these are a bit of fun – but others can have implications for your property's look, thermal efficiency and even value.

Join us as we run through eight common misconceptions about the humble window.

1. Are windows liquid?

Misconception: yes, windows are a liquid.

Fact: they're made of solid glass.

Explanation: windows used to be thicker at the bottom than at the top – a fact which has led some people to think that they must be made from a liquid that has "dripped down" over time.

However, a liquid is something that fits and moulds its shape to its container. A solid, on the other hand, is something that has a definite shape and volume – and glass falls into this category.

The reason that windows used to be thicker at the bottom is that it gave them added stability.

2. Did windows used to be taxed?

Misconception: no! Surely not?

Fact: yes, and the more windows you had, the higher the tax!

Explanation: in 1696, window taxes were introduced.

Like beds and other household items, windows at this time were luxury goods – so the rich bore the brunt of the tax. Households with fewer than ten windows were exempt.

However, the policy backfired as people found ways to dodge the tax. Windows were bricked up and new houses were built with as few windows as possible. This meant that renters were paying top prices for properties with little to no light or ventilation.

3. Do windows increase property value?

Misconception: yes! Any window does.

Fact: windows can add value, but not all the time.

Explanation: when considering installing new windows, the first thing to consider is the age and style of your property. Changing your windows to a style that doesn’t suit your house can devalue it if you’re hoping to sell.

Timeless styles tend to add value more than the latest trends – as do windows that complement your house's colour scheme.

4. Can anyone install a window?

Misconception: yes! It's a great way to save money.

Fact: it’s possible – but not recommended.

Explanation: if you're a fan of DIY, it can be tempting to cut down on costs by installing your own windows. But glass installation requires a lot of skill, training and expertise.

Fitters have to follow very precise instructions to make sure that the window is installed correctly. A bad job will only lead to leaks, drafts, and other issues – not to mention expensive repair jobs further on down the line.

5. When should I open my windows for ventilation?

Misconception: you should open your windows all year round to let in the fresh air.

Fact: it may not be wise to have your windows open all year round.

Explanation: in some weather, opening your windows is a great idea. But in the cold of winter or the heat of summer, it's not always the most energy-efficient option.

A better approach can be to use a mechanical ventilation system or a window design that's been optimised for airflow. These can also help when the air outside is polluted – or when it's hay fever season.

6. Are my windows the main source of heat loss and drafts?

Misconception: of course! What else could it be?

Fact: new windows can help keep your house insulated and drafts normally enter through doors.

Explanation: this myth probably comes from the fact that single-glazed windows can let in drafts and contribute up to 25% of the heat lost by a property.

But modern double- and triple-glazed windows are far better at insulating your property – and they let in next to no draft.

In colder climates, triple-glazed windows can provide the insulation you need – but a lot of the time, double-glazed windows are energy-efficient, cost-effective, and good at keeping out unwanted noise.

7. Are my windows weak security points?

Misconception: yes – windows always create security risks.

Fact: it depends on the type of window that you have.

Explanation: yes, glass is always going to be easier to break than a brick wall. But does the type of window you own make any difference?

The answer is a resounding "yes". Double-glazed windows often come with enhanced safety features like shatterproof glass, child restrictors and multi-point locking. These make it extremely hard for burglars to make a sneaky entrance.

If you're especially concerned about your security, you could consider a polycarbonate safety shield. Polycarbonate is 250 times stronger than glass – so it's a great way to burglar-proof your windows.

At Calder Windows, all our windows come with toughened glass and multi-point locking as standard – so you don't need to worry about security risks .

8. Does more expense mean better quality?

Misconception: a lot of things work that way, so I’d say yes!

Fact: higher costs don't always translate into better quality when it comes to windows.

Explanation: many factors can affect the price of windows – the number of panes used, the style of the window, the materials it's made of, and current industry trends, to name but a few. However, a hefty price tag doesn't mean the best window you can buy.

Your best bet is to shop around and find the best deal for you.

Are French doors really French?

Mon, 11 Sep 2023 08:00:01 GMT

We call them "French doors" – but how French are they, exactly? Find out the answer to this burning question – and more – in our 5-minute guide.

Don't be fooled by things that are named after countries. Half the time, these locational labels are as fake as imitation leatherette.

English muffins? Actually American. Scotch eggs? English (sorry, Scots). French toast? English too. We could go on…

And wait until you hear about French doors .

Yeah, they're from Siber… Oh. Wait. They're actually French.

It turns out French doors were invented in France at some point between the 16th and 17th centuries. (And everyone has thanked their inventors ever since – especially us!)

As they're such a popular home improvement here in the UK, we've decided to look at French doors in a little more detail. Here are all the FAQs you need to know about France's most famous export. (In the world of fenestration, at least.)

Where are French doors used?

French doors are used to separate spaces and capture as much natural light as possible. They serve to illuminate a room and provide a quick route to the great outdoors.

Up and down the UK, French doors are commonly used as openings into gardens and patios. They can also be used in summer houses, outdoor offices and workshops.

Bi-folds, those concertina-like cousins of French doors, are now standard in many new-build homes.

Do French doors open all the way?

Most French doors are hinged so they open all the way (or at least until they hit a solid object).

They're often referred to as two-hinged doors as they meet in the middle and open outwards – usually into an outside space.

This is one reason why they're so desirable – other than the fact they flood your living space with natural light.

The beauty of the French door is that you can choose to have just one door open or click a few buttons on the centre frame and create a double-door exit.

Bi-folds vs French doors

Bi-folding doors and French doors look similar at first glance. However, there are a few differences you should be aware of.

While they're both amazing at letting light into your home and come in a variety of materials and colours, this is pretty much where their similarities end.

French doors are two separate doors that meet in the middle and can be opened individually or together. Bi-folds work on a track mechanism and are made up of multiple doors that 'stack' horizontally – a little like a concertina.

Bi-fold fans love this feature because it saves space and helps to create a sense of continuity between indoors and out. With a wide set of bi-folds, you'll feel like your garden is only ever a step away.

However, French doors can be the better option for small spaces that aren't large enough for bi-folds. Because they open outwards, they don't demand any clearance indoors.

It's another win for French doors when we talk about price, as their simplicity also means they're more cost-effective.

Don't get us wrong – bi-fold doors are hardly the preserve of lottery winners. However, French doors reward you with lots of light and a classic look for a very reasonable upfront investment.

Can French doors have screens?

The simple answer to this is, yes!

Allow us to elaborate.

The most common option for French doors is retractable screens. These help maintain a level of privacy but can be rolled back to let in lots of glorious sunshine.

The screens fully cover each window panel and meet in the middle, with the option to keep one side retracted while the other covers half the window.

An alternative to screens is blinds, whether that be a roller blind or a manual fold-up blind. All can help to keep your home feeling bright and airy while keeping you safe from prying eyes.

How safe are they?

Last but not least, how safe and secure are French doors?

French doors are just as secure as any other door – especially if you buy from Calder. All our doors and windows are supplied with high-quality locking mechanisms for total peace of mind.

Besides, the greatest risk with these types of doors is when they're not installed properly. Settle for a bodge job, and you run the risk of various issues – from the doors not working correctly to reduced security.

With that being said, if you're on the lookout for some French doors to brighten up your living space and add an extra sprinkle of style and elegance, look no further than Calder Windows.

Not only have we got the goods but our installers have a fantastic reputation with decades in the trade.

And once your new doors are fitted you will get a 10-year warranty and aftercare when it's needed. Nice!

Double glazing vs. triple glazing: how much better is it, really?

Fri, 08 Sep 2023 08:00:00 GMT

Let's compare double glazing and triple glazing. Is triple glazing really worth it? The experts weigh in on insulation, noise, comfort and value.

When it comes to choosing windows for your home, there are lots of factors to consider. Beyond aesthetics, stained glass, shapes and tints, there's one question that often still baffles homeowners.

Is triple glazing worth the investment? Can an extra pane of glass really make that much difference?

Well, it's a little more complex than that, actually.

Let's quickly break down the differences between the two.

Double glazing vs. triple glazing

Double glazing is a type of window with two glass panes separated by a gap filled with gas. This gap helps to insulate the home and reduce heat loss.

Triple glazing , meanwhile, has three glass panes separated by two air gaps. This provides even more insulation and heat loss reduction, along with several other benefits.

So, we know triple glazing has more going on in its inner workings, but how much better is triple glazing than double glazing?

Insulation

Triple glazing is between 40% and 50% more thermally efficient than double glazing, especially if the frame is installed correctly by experts like us.

So, it's fair to say triple glazing is significantly better at insulating your home than double glazing. Better insulation means less heat loss and less hard work for your central heating. This is especially important nowadays since energy prices remain unpredictable.

Environmental factors play a part too. Using triple glazing in your doors and windows isn't just a money-saving measure. It can also help to lower your household carbon emissions.

And in the world of energy-saving fenestration, it all comes down to "U". (Yes, U.)

The U-value of a window measures how good it is at stopping heat transmission – from inside to outside and from outside to inside. The lower the U-value, the better the insulation. On average, triple glazing has a U-value of 0.8, while double glazing has a typical U-value of 1.6.

You may pay more upfront for triple glazing. In reality, however, the difference it makes to your home insulation can lead to significant savings on your energy bills – especially in the winter months. Ultimately, the slightly higher price tag could pay for itself.

This is especially true if you can ditch the cost of heavy curtains in favour of better- insulated windows . (Now that's a choice that you won't have to lose sleep over.)

Noise reduction

Speaking of losing sleep (or, more precisely, not losing sleep) …

If you've ever lived by a main road, a train station or a nightclub, you'll understand the importance of noise insulation when it's time to draw the curtains for the night.

How does triple glazing fare when it comes to noise reduction?

Well, it has an extra layer of glass and an extra layer of gas. These extra layers add up to better sound absorption. There's simply more "stuff" for the audio waves to pass through.

As a whole, triple glazing has been shown to absorb 50% more sound than other kinds of windows.

If you live in a noisy area, value peace and quiet and are willing to pay a little extra, triple glazing should definitely be on your radar.

Security

Although glass is often considered a fragile material, you'd be surprised how much difference an extra pane of glass can make when it comes to the strength and security of your windows.

Because triple glazing uses three panes of glass, it's more difficult to break through a triple-glazed window. This makes it more secure against intruders – and more of a pane (get it?) for criminals.

So if you're tallying reasons to choose triple glazing over double glazing, add security to that list. Who'd have thought one extra pane of glass could make life so much harder for those pesky burglars?

Return on investment

According to The Eco Experts, homeowners are likely to see a return on investment if they sell their property after installing double or triple glazing.

Installing new windows can increase the value of your property by improving its Energy Performance Certificate (EPC) rating. Properties with good EPC ratings can sell for up to 14% more than properties with poor EPC ratings.

As triple glazing is more energy efficient, it's likely to improve your home's EPC rating and may prove to be an enticing selling point for potential buyers.

Condensation reduction

No more drippy windows and wet window sills. Triple glazing is great for tackling condensation issues.

Condensation occurs when there's a temperature difference between window glass and indoor air. Triple glazing's multiple panels can notably reduce this risk because the innermost pane, inside the home, remains warmer. See how those triple-glazing insulation qualities go a long way?

However, it's important to note that while triple glazing can and should substantially reduce condensation, it's not guaranteed. You might still see condensation if your home has certain defects or broader humidity and ventilation issues.

What's the verdict?

Of course, triple glazing is a little more expensive than double glazing. But it's easy to see why.

The additional cost is usually offset by the savings on your energy bills, the increased value of your home and – of course – the peace of mind you feel knowing that your home is quieter and more secure than before.

If you're looking for the best possible insulation, noise reduction , security and value for your home then triple glazing is the way to go.

And if you are still unsure whether to choose double or triple glazing, why not consult the professionals?

9 tips for making the most of a conservatory

Mon, 04 Sep 2023 08:00:01 GMT

Is your conservatory feeling a little worn out? Give it a new lease of life with our tips. (Trust us – you'll soon fall in love all over again.)

We love conservatories – and so does the population at large.

In 2013, nearly one in five houses had conservatories. And according to some sources, their popularity is on the up and up.

But as the flames of love burn bright, so the fire extinguisher of real life squirts powerful jets on our dreams.

When you've got work and bills and more bills to think about, it's all too easy to let that dream conservatory become a little, well, neglected.

There are many reasons why your conservatory might lose its lustre. Perhaps family circumstances have changed. Perhaps budget constrictions came into play. Maybe you just don't have time to keep it looking shiny and inviting.

But it doesn't take much to make your conservatory as good as new again. With a few well-placed furnishings or a little investment, that sunroom could become your favourite room in the house.

Read on for our top tips on reimagining and redesigning your conservatory. It's time to fall back in love…

Quick fixes

1. Transform it into a calming space for "me time"

Picture this: a space that's all about you. A space that can whisk you away from the chaos of the world and into a realm of relaxation.

It doesn't have to cost the earth – small additions can really transform a conservatory. Think scented candles, mood lighting, cosy cushions and blankets.

So, treat yourself to some tempting snack jars, banish those pesky screens and settle into some "me time". Whether you want a spa vibe, a meditation zone or just a cosy spot to read a book, get that imagination flowing and create a space that works for you.

2. Create a dedicated games zone

Why not give your conservatory a seriously fun makeover? Say hello to your future games room!

Maybe you want somewhere for the kids to play or just want to settle down with your newest game console? A dedicated gaming zone is a luxury – but if you've got an unloved conservatory, it could present the perfect opportunity to treat yourself.

You could go retro, with neon lights, tabletop games and an arcade feel. Table football anyone? Air hockey? Fruit machines? Or maybe you'd prefer a sleek and minimal space to focus on your digital games?

In any case, a dedicated games room can help calm the chaos of a fun-hungry household. Sick of tripping over wires and controllers? Or treading on Lego? Consolidate all your games-related paraphernalia into one place. Game on!

3. Bring outside inside with a garden room

Imagine stepping into a lush oasis in your own home. A natural wonderland, where you can surround yourself with potted plants and hanging baskets – and perhaps even fruit trees or veggies.

A garden room lets you soak up all the goodness a garden provides, even if the weather's bad. Natural light pouring in through the glass will make your plants thrive and create a bright, uplifting space in which to potter and unwind.

And unwind you will. Having greenery in the house is known to be good for wellbeing, as well as looking gorgeous.

You could even have an indoor water feature and relax to the sound of a trickling stream. Ahh…

4. Disco room! (Yes, seriously)

Why not go full Ibiza club vibes and transform your tired conservatory into a laser-lit club dance floor?

Invite friends over, turn on those lights, plug in the speaker and just let your hair down. Boogie, baby!

At home, it's easy to get distracted by chores and the realities of life. But everyone needs to let loose sometimes – and your unused conservatory could make the perfect entertainment centre for your home.

5. Get some blinds or curtains

This one sounds so simple. But it's amazing how many people limit their options when it comes to blinds and curtains in conservatories.

It can be lovely to have a bit of privacy when you want it – and getting window coverings fitted is the obvious first fix.

Are you creating a cosy Zen den? A clean office space? Either way, blinds and curtains can go a long way to transforming your conservatory from stark to welcoming.

Bigger fixes

The above suggestions are all well and good if your conservatory is in good shape. But let's suppose your problems are more than skin deep. Maybe your conservatory was fitted years ago – or you avoid it at certain times of the year due to the temperature.

Whatever the issue, there are various options for upgrading your conservatory and here at Calder Windows, we've got you covered. We outline some of the best options below.

6. Replace the glass

Are you not using your conservatory because it's a bit old or cold? Replacing the glass can be a great way to give your conservatory a facelift, as well as improve insulation.

Glazing technology has come a long way in recent years. New double or triple glazing will look great and cut your energy costs. Win-win!

7. Replace the roof

Give your conservatory a new lease of life with a smart-looking, insulating roof.

Here at Calder Windows, we offer Supalite roofs . These manage temperature fluctuations, look great and can last for decades.

8. Make it open-plan

Have you soured on your sunroom because it feels cramped or too separate from the rest of the house? Why not go open-plan?

Sometimes a simple solution can really change the feel of a conservatory – and opening up the space is sure to renew your enthusiasm.

Best of all, it's not just your conservatory that benefits. Going open-plan can create more space and allow more sunlight to enter your home.

Bi-fold doors can give you the flexibility to open and close off your conservatory as you wish. So, take a look at our range of bi-folds and start getting inspired.

9. Replace it with an orangery

Maybe it's time for a proper change. Perhaps you're ready to swap that conservatory for something that feels a little more like home.

Orangeries are gaining popularity year on year. They feel a little more "indoorsy" and often have brick walls with large windows, as opposed to floor-length glass panels like conservatories.

If you're considering an upgrade, feel free to get in touch with Calder Windows. We're experts on orangeries and conservatories – and we have decades of experience to boot.

(Oh. And you aren't obliged to grow oranges, by the way!

Conservatory styles explained

Wed, 02 Aug 2023 11:32:28 GMT

Conservatories can be a great addition to your home and garden – and they come in myriad styles. Discover more in our blog post.

A conservatory can be a gleaming addition to any home and garden. They're beautiful, practical and versatile – equally good as a sunroom, a greenhouse or a chill-out zone.

Perhaps you want to grow some plants that need a lot of sun – bringing a hint of the tropics to your home.

Or perhaps you're a bit of a houseplant yourself and want to catch some rays from a cosy hideaway.

Or are you an entertainer, looking for some extra space to host guests?

Whatever you use it for, a conservatory can add space, colour and light. But as well as its function, there's the question of style.

A conservatory is like a bowtie. Some people want one that spins, flashes and squirts out water – a real statement piece. Others want something that blends subtly into their outfit, matching its shades, materials and lines. And the rest of us fall somewhere between these two extremes.

It's no different with conservatories. Just as the paint for the frames comes in a hugely varied range of colours, so the style itself can be more or less extravagant, more or less subtle, depending on your personality and taste.

Conservatories suit many occasions and many types of homeowners. So it's no surprise that they also come in myriad styles – and here at Calder Windows, we cater for many of them.

In this article, we look at six popular types of conservatories to help you choose – from traditional to modern, from minimalistic to ornate.

Our first stop is the Victorian times. So, put on your best bowler hat and hop in our time machine…

Victorian-style conservatories

If you were playing a game of Pictionary and had to draw a conservatory, we're confident that this is the kind you'd draw.

Its ridged roof, bay window and octagonal floor plan are inseparable from the Victorian era. Having one of these in your garden is like commissioning your own mini Crystal Palace or Kew Gardens.

Where once they were made from glass and steel, they're now made from toughened glass and either uPVC or aluminium.

These changes in materials mean that you get that vintage look without having to suffer from vintage draughts, roof noise and peeling paint. Those guys had the look – but they didn't have the technology to make it durable and energy-efficient.

If you want to make a statement and enjoy expansive views of the garden, a Victorian-style conservatory could be the one for you.

Edwardian conservatories

Edwardian conservatories are Victorian-style conservatories' bigger, more austere cousins. They're less flash – but no less elegant.

They have the same ridged roof as their Victorian predecessors. The key difference is the floor plan. That quirky Victorian octagon has been replaced by a rectangle designed to maximise floor space.

Hip-back or double-hip Edwardian varieties are available for properties with lower rooflines such as bungalows.

An Edwardian conservatory is a great choice if you or your plants want a little more room to stretch out.

Gable-end conservatories

A close relative to the Edwardian conservatory, gable-end conservatories have an upright roof that resembles a house's gable-end.

In other words, the roof doesn't slope backwards but juts upwards, adding extra height and a touch of grandeur.

Like the Edwardian conservatory, it has clean lines and a more modern aesthetic. However, it's not suitable for lower properties – you need a roofline high enough to accommodate the apex.

Lean-to conservatories

Also known as Mediterranean conservatories or simply "sunrooms", lean-to conservatories have a sloping roof. The longest wall is fixed to the house.

This is one of the simpler designs and it's usually the most affordable. It's simple, practical and versatile – and a bit more contemporary-looking than the others we've looked at.

It's also good for lower buildings as the roof height is customisable.

If you're after a mini-greenhouse or a snug chill-out space, a lean-to could be for you.

Orangeries

Orangeries originated in the Renaissance, where advances in glassblowing allowed for the production of large glass windows for the first time.

These were used to maximise the amount of sunlight in a room – meaning that wealthy homeowners could grow citrus fruits and exotic plants all year round.

Orangeries are made from brick, with large windows and a flat roof with a glass lantern that lets the light come flooding in.

An orangery means business. It won't blend in like a lean-to – it's at the more extravagant end of things, perhaps closest to the Victorian-style conservatory.

But as well as being a showpiece, it has all the advantages of other types of conservatories. You can use it as a hothouse, a children's playroom, a place to unwind, a place to entertain or any combination of the above.

Other shapes

Conservatories are easy to customise. Want your floor plan to be P-shaped, L-shaped, T-shaped or U-shaped? There's nothing stopping you.

Lantern roofs

Where a skylight sits snugly in the pitch of the main roof, a lantern roof is more like a crown. It's an independent structure that juts forth majestically from the roof into the sky.

As well as being easy on the eye, lantern roofs let in huge amounts of light – great for humans and plants alike.

A lantern roof is a bold statement – but it's an undeniably impressive one.

About us

Here at Calder Windows, we stock a wide range of conservatory products – and we work with you to create the right design for your property. Victorian-style? Orangery? Lantern roof? We've got you covered.

We're a family-run firm, so you know you're never getting a sales spiel – just clear, honest communication about what you need and what we offer.

Like everything else in our range, our conservatories are both sturdy and elegant. They add space to properties of every style with no sacrifice to safety or thermal efficiency.

Bells, knobs and beyond: a guide to door hardware

Wed, 02 Aug 2023 11:27:55 GMT

Bells, handles, knockers and letter boxes – they come in all shapes, sizes and materials and can add character to your home. Learn more in our blog post.

Sometimes, when you're shopping for a door, you just want a door – something sturdy, secure and easy on the eye. Other times, you want to make a statement.

If your home is your castle, your front door is your calling card. It can reflect your personality, be it restrained, flamboyant or anything in between.

One way to take the postman's breath away is by entering the world of door hardware – those handles, knobs and knockers that enhance your door in the same way that jewellery can tie your outfit together.

The market is heaving with options. Door furniture comes in a wide range of styles, colours and materials.

So if you're wondering how to increase your kerb appeal – or simply want to feel satisfied each time you come home – join us as we run down some of the most common types of door hardware.

It's more interesting than you might think.

Handles and knobs

There are several types of door handles and doorknobs.

You can either get a "keyed' doorknob or a so-called "dummy doorknob". This is like a sewn-up pocket on a pair of jeans – strictly for aesthetics with no practical function.

Doorknobs can make a real statement. They've come a long way since being patented in 1848 by Osbourn Dorsey, a 16-year-old African-American inventor – but they've always had the potential to combine style and function.

In terms of handles, there are push-pull handles – often used in commercial settings where the door is constantly in use – or long lever handles, typically found on uPVC doors.

For something so commonplace, doorknobs and door handles play a surprising role in cinema – from the talking doorknob that Alice has to fit through to enter Wonderland to the red-hot doorknob that Kevin uses to deter the robbers in Home Alone .

Letterboxes

Letterboxes are another great example of how the mundane can be beautiful. And their history is actually quite fascinating – no, really.

The story starts in 1516 when Henry VIII founded Royal Mail. Back then, it was the recipient who paid for postage – not the sender (imagine!)

So in order to deliver a letter or parcel, you had to do it yourself if you wanted to collect your postage fee.

Fast forward to the 1830s and the Post Office was losing money. A teacher, inventor and social reformer named Rowland Hill had a solution.

He argued that prepayment would make the transfer of letters cheaper, safer and quicker – and that if prices went down, poorer people would start sending post, resulting in greater profits for the Royal Mail.

And it worked. In 1840, the year that saw the introduction of the penny stamp in the UK, the number of letters doubled.

This revolution in the postal service meant that the sender no longer had to collect postage fees. Letters could be left at a property without fear of monetary loss, hence the advent of the letterbox.

Letterboxes were touted as secure – something that mattered a lot to people at a time when letters were the primary form of communication.

Over the years, letterboxes have been made in a staggering number of styles and materials – from cast-iron and solid brass letter plates in Victorian and Edwardian times, to curvaceous art nouveau specimens, to today's modern oblong fittings.

A good-quality, aesthetically appealing letterbox can liven up any front door – so it's worth taking a look at what's available.

Knockers

Unlike letterboxes, door knockers have been around for ages. In fact, the earliest example dates from Ancient Greece.

But despite the arrival of doorbells, knockers are still a common feature in the UK – either because it's an economical choice or, contrariwise, because you want to impress the Amazon delivery driver.

There are two main types – either screwed to the door or attached from the inside with bolts.

Door knockers have always brought out the impish side of ironmongers. In Spitalfields, London, you can see knockers shaped like women's hands, Sphinxes and even an upside-down dolphin.

One of the world's most famous doors is at 10 Downing Street – and it's partly memorable because of its black iron knocker in the shape of a lion's head.

Writers, too, have turned to door knockers for dramatic tension. Just think of the famous "porter scene" in Shakespeare's Macbeth or the knocker that morphs into Jacob Marley's face in A Christmas Carol.

More everyday, but no less stylish, there are a whole host of knockers on the market in a variety of styles and materials.

Locks

Locks aren't just there for safety and they're not just there for beauty. They can also influence your home insurance premium.

Many insurers consider the safest model to be a five-lever mortice deadlock that adheres to BS (British Standards Institute) 3621.

In commercial properties, electronic locks are on the rise – and they're also starting to appear in domestic settings.

While they're undeniably convenient, they present a couple of challenges. First, they're connected to Bluetooth, which is vulnerable to hacking. Second, they're seen by some insurers as a security risk.

Just like knockers, knobs and letterboxes, locks can be beautiful. Have a browse – you'll be surprised by the range of colours, designs and materials available.

Doorbells

Electric doorbells have been a fixture of British life since the early 1900s. Today, you can still get a classic model – or invest in a smart doorbell with a video stream for added security.

And of course, you can choose the right ringtone for you – anything from a classic "ding-dong" to Beethoven's Fifth .

Want to doll up your door?

Here at Calder Windows, we stock a wide selection of doors – ranging from the minimalistic and elegant to highly customisable statement pieces.

Whether you're looking for a uPVC front or back door, a door with a traditional timber look, french doors, inline patio doors or uPVC stable doors, we can help. We provide a complete front door fitting service – and all our designs come with extensive opportunities for decorative hardware.

Want to make your door something you look forward to coming home to? Take a look at our range online – or pop into our showroom in Normanton to see what we offer.

Can you paint uPVC windows?

Wed, 02 Aug 2023 11:23:41 GMT

Are your uPVC window frames looking a little worse for wear? You can either repaint them or get them replaced. Find out more about the pros and cons.

Here at Calder Windows, we're big fans of uPVC for window frames.

It's no accident that it's been a staple choice of material for British households since the 80s. It combines toughness, durability, security and energy efficiency with huge aesthetic potential. These days, you can get them in every shade under the sun.

And they're long-lasting. Our range comes with a 10-year warranty as standard – and, if you look after them well, you can expect them to last for upwards of 20 years.

But even a trusty old workhorse can start to sag at the knees eventually. After a while, your once-radiant uPVC frames can start to look, well… a little old and tired.

If this sounds like you, you may be looking for solutions. There are two routes you can go down. The first is to get them replaced by a professional and enjoy that fresh off-the-shelf look. The other is to give them a new lick of paint.

Whichever option you choose, it can be well worth doing – not only for your own sake but also to boost your "kerb appeal" should you come to sell the property.

Things to keep in mind when painting uPVC windows

Whether you have white or wood-effect uPVC frames, it's entirely possible to repaint them. However, before you drive off to the home improvement store, there are a couple of things to take into account.

First, a repainted uPVC frame can look fresh and appealing – but it most likely won't be quite as durable as a newly fitted frame.

And second, it takes work. A surprising amount of work, in fact. It's a bit like doing your own plumbing. If you've got the time, skill set, equipment and inclination, go for it! But if you lack even one of those things, you may find it easier to call in the professionals.

There are paints on the market that have been specifically created for uPVC. This is because you need paint that bonds to the surface. uPVC is tough, sure – but it can still expand and contract in the heat a little. If you don't get the right paint, you can end up with some unappealing textures.

The same goes for any other uPVC object – be it a pipe, gutter, soffit, fascia board, garage door or patio door frame.

Perhaps you've inherited a fading or ageing set of uPVC window frames. Your first port of call is to wash them down with warm water and detergent.

If that doesn't make the difference you desire, you can think about repainting. But remember – if they're nearing the end of their earthly span, it may be more convenient just to get them replaced.

How to paint uPVC window frames

Simple! Just grab a tin of paint and slap it on, right? Well, no.

It takes preparation, elbow grease and a favouring wind – because the weather will contribute to the success or failure of your attempt.

First, you should cover any areas that don't need painting with newspaper held in place by painter's tape.

You need a clean, dry surface to work with, clear of anything that will prevent the paint from fully adhering to the plastic.

That means scraping or brushing off any unwanted bits and bobs with a stiff bristle brush, then degreasing the frame with hot soapy water and a kitchen scourer.

Next up is sanding. With fine grit sandpaper, lightly sand the surface, then brush it and wipe it until it's dry and dust-free.

Before you crack open the tin of paint, you need to apply primer to the frame and dry it according to the manufacturer's instructions.

When painting the frames, you need the right weather for the job. If it's a scorcher, the paint will dry too quickly and end up splodgy or uneven. But if it's a nippy one, the paint won't dry properly.

Your best bet is to get started on a warm, dry day when the paint will set nice and evenly.

You'll need two full top coats. There's a huge range of colours on the market, so make sure to shop around for the right shade for you and your property.

In between coats, you'll want to lightly sand the surfaces. When – and only when – the paint is 100% dry, you want to remove the tape. Any sooner and you'll be left with an uneven line.

Finally, it's worth remembering that paint doesn't harden straight away. Once you've finished the job, leave it to "cure" for a few days.

Frequently asked questions

Should I use a roller or a brush?

If you're painting a window frame, a brush is the easier option. But if you're painting a uPVC door with large flat areas, a foam roller is better.

Can you spray a uPVC frame?

Yes, and this can give you a smooth "factory" look. It's harder than using a brush, however, and requires both practice and space. You'll need to protect areas that don't need painting from the spray.

Can you repaint a dark frame with a lighter colour?

Absolutely. You'll just need a lot of primer.

Can you repaint a brand new uPVC frame?

New uPVC frames are coated with an extra layer of plastic that gives them their showroom shine. Ideally, this shouldn't be painted over for at least 12 months.

Can I use a cheap alternative to uPVC paint?

You can, but it's not advisable. Other types of paint will leave coats that crack, blister and peel – so you'll just have to remove, wash down and repaint them in the long run.

When is it better to buy new?

When it comes to home improvements, DIY is always an option – and aside from anything else, you'll have the satisfaction of having done it yourself.

But if this all sounds like too much work, there's always the option of replacing your uPVC frames altogether.

Durability is one of the best things about uPVC – but if your frames are getting on a bit, slapping on a new coat of paint won't increase their shelf life.

In most situations, you're better off getting an experienced, reputable fitter to replace your uPVC frames in the right hue for you.

Is it time to get triple glazing?

Wed, 02 Aug 2023 11:18:40 GMT

Is triple glazing worth it? Learn about the positive impact it can have on energy efficiency, noise levels and the saleability of your home.

Do you want to improve the thermal performance of your home? Are you tired of being kept up by traffic outside your window? Are you looking for ways to increase the market value of your home ?

If any of these apply to you, it may be time to invest in triple-glazed windows .

Triple glazing has become the norm in cold climates like Scandinavia and Canada, where trapping as much heat as possible in the home is a priority.

But it can make a difference here in the UK, too – especially at a time when energy bills are on the up and more and more homeowners are thinking about their carbon footprint.

Before we go any further, we should put our cards on the table. Triple glazing is more expensive than double – there's no way around it. But as with many big investments, it reaps dividends in the long run.

We're confident that in most situations, triple glazing will improve the comfort and thermal performance of your home.

How does triple glazing work?

Triple-glazed windows consist of three layers of glass that are sealed in an airtight unit. Between each pane is either air or an inert gas like argon, krypton or xenon.

These gases are useless at conducting heat – which makes them ideal for technology that aims to keep heat leakage to a bare minimum.

Triple glazing is heavier and more insulating than double. It's not much different from wrapping up warm in winter. If double glazing is a vest and shirt, triple glazing adds a jumper.

It's all about comfort. Even if your property's walls, roof and floor are well-insulated, poor glazing will lead to cold spots on the windows. Triple glazing ensures the warmth is distributed evenly throughout your home before you even consider putting the heating on.

That single extra pane of glass can make a world of difference. By retaining heat, it helps you to curb your energy usage. At a time when energy prices are spiralling and there's an emphasis on sustainability in the housing sector, it can be a prudent investment.

It's also more secure than double glazing. That extra thickness makes it harder to break.

And that same thickness does wonders for noise reduction. If you're fed up with having your sleep disrupted by the traffic outside your window, it could make a big difference.

What is a window's U-value?

This is a term you'll come across a lot when researching different types of windows. It's clearly important – but why?

U-values are a way of measuring a window's thermal performance – in other words, how effective it is at keeping the heat in.

Your home has an overall U-value which your windows contribute to. Having triple-glazed windows lowers the U-value – meaning they're providing better thermal efficiency.

It's especially important at a time when the housing sector is being pushed to focus on energy efficiency as part of a general drive to reduce carbon emissions.

Since June 2022, new buildings are required by law to have windows with a U-value of 1.4 W/m2K or less. Triple glazing is around 0.8 – so well ahead of the curve. Compare that to double glazing's U-value of around 1.4 and you can see why it's flavour of the month.

As well as U-values, you may come across a letter-based rating system. This is the British Fenestration Rating Council's way of measuring thermal performance. It goes from A++ (highly energy positive) to E (far from ideal).

Keeping heat in

Triple glazing has a positive impact on your energy efficiency by providing a thicker barrier between inside and outside. That airtight unit which contains the panes of glass means you'll reach for the central heating button less and less.

On average, triple glazing is between 40 and 50% more thermally efficient than double, especially if the frame is properly installed and insulated.

That means lower heating bills, a better U-value and a slimmer carbon footprint.

As well as warming you up in winter, triple glazing can make a difference in summer by reducing the chances of overheating.

Noise reduction

If you live in a busy area, triple glazing can help to dampen the noise.

But as with heat, it works both ways. As well as keeping noise out, it can keep it in. This can be invaluable if you have a large family or a job or hobby that means you make a lot of noise.

Highly secure

Security should never be an afterthought – and here at Calder Windows, it's baked into everything we stock and every job we do.

Triple-glazed windows are harder to break than their double-glazed counterparts and usually have a toughened middle pane.

Reduce condensation

Tired of dripping windows? Triple glazing lowers the chances of condensation in your property, improving comfort as well as your thermal performance.

Improve your property's saleability

All of the above qualities have the potential to boost the market value of your property.

Triple glazing and double glazing look the same – so the effect on saleability can sometimes be overlooked (literally).

But at a time when EPC ratings are required when renting or selling, your energy efficiency is part of your sales pitch. The issue of sustainability isn't going anywhere, so the thermal performance of your property is likely to become more and more relevant going forward.

The bottom line

If you're looking to improve your energy efficiency, reduce noise or add value to your home, triple glazing could be the way forward.

Yes, it's pricier than other options. However, it's a valuable investment for your property that you won't regret – and which, in time, will pay for itself.

What are Crittall doors?

Mon, 03 Jul 2023 11:59:02 GMT

Crittall doors are a type of metal-framed, wall-length window that can be used for patios, partitions and extensions. Find out more about this classic style.

Sometimes, when you're renovating or fitting out a house, you just want a window. A nice, sturdy, functional window that keeps the burglars out and the heat in.

Other times, you want a bit of high-end pizzazz. One popular option is the Crittall-style door – a wall-length metal-framed window that dates back to the late 19th century.

Even if you don't know the name, you'll know one when you see it. They've been used everywhere from the Houses of Parliament to Singapore's financial district.

At first, they were synonymous with industry – and poor heat retention. But they soon became inextricably associated with early 20th-century architecture.

But while you might think they're the preserve of draughty corridors of power, they can blend beautifully with a domestic setting – and these days, they're made with up-to-date thermal efficiency in mind.

They're a popular choice for patio doors , where they frame the garden or courtyard and let the light come flooding in. But they can be used for partitions, extensions and orangeries too.

Slim, elegant, sturdy and minimalistic, these are windows that make a statement. Depending on where they're installed, they can conjure up thoughts of 19th-century industry or 20th-century power.

Whatever effect you're going for, their frames – as sleek and clear as brush strokes on canvas – give your home a high-end look.

What are Crittall doors?

Crittall is a registered trademark. The terms "Crittall door" and "Crittall window" refer to those made on-site in Essex by the trademark holders.

In practice, the word is used as shorthand for any door in that style. But in the interests of exactness, retailers use the term "Crittall-style".

The Crittall story starts in Braintree, Essex in 1849, where Francis Berrington Crittall bought an ironmongery. After his death in 1878, his son Francis Henry Crittall took over and steered the factory towards the production of metal windows.

And it's going to this day, still on Essex soil. For nearly 150 years, they've made metal-framed windows across the UK – but also in South Africa, India, Australia, New Zealand, Germany, the USA and Shanghai.

Crittall also designed and built a model village for its workforce.

In the late 1920s, Braintree was no longer able to accommodate Crittall's employees, who by this point constituted 10,000 of the 18,000-strong population.

So Francis Henry Crittall funded Silver End Model Village near Witham. His second son, Walter "Pink" Crittall, did most of the artistic and technical work.

The village is full of early modernist designs – and is also home to the largest village hall in the UK. This building is to the average village hall what Disneyland Paris is to Chessington World of Adventures. It features a dance floor, cinema, library, snooker room and even a health clinic.

Famous Crittall doors and windows

1. New Farm, Essex

"Pink" Crittall didn't only work on Silver End. He also designed New Farm, a six-bedroom house with five acres of gardens and orchards, where he lived from the mid-1930s onwards.

Just a few miles from the factory at Braintree, New Farm is like a modernist architect's Pinterest board that's come to life.

It boasts countless memorable features – pale pink walls, turquoise Crittall windows, an inlaid wooden star on the hallway floor, glass portholes, a three-storey tower of glass and steel and an octagonal dining room.

One thing's for sure – Pink loved light. The house is flooded with it. It's one of the things that Crittall doors do best.

2. Coventry Cathedral

In the West Midlands, Coventry Cathedral boasts its Great West Screen or "Screen of Saints and Angels".

This imposing glass facade was engraved by New Zealand-born John Hutton and features 66 saints and angels.

When Hutton died, he requested that his ashes be buried at the foot of the window. If you look down at the pavement, you can see the inscription.

3. Royal Shakespeare Theatre, Stratford-upon-Avon

Also in the Midlands is the Royal Shakespeare Theatre at Stratford-upon-Avon. This iconic building's steel windows were restored in a prestigious project between 2007 and 2010. Glass was removed, frames were painted and everything was restored and cleaned before the great refitting.

4. Lots of buildings (and a boat) in London

In London, many centres of financial and political significance have Crittall doors – the Houses of Parliament, the Public Record Office and the Tower of London, to name but three.

And if you're walking along the Thames path in Hampton, you might spot the Astoria , a grand houseboat built in 1911 for English theatre impresario Fred Karno.

Karno was the man who discovered Stan Laurel and Charlie Chaplin, among others. He commissioned the boat with the express intention of having the best-looking vessel on the river.

The boat is framed in mahogany, fitted with plenty of Crittall windows and crowned with ornate metalwork.

In the 1980s, the Astoria was bought by Pink Floyd guitarist David Gilmour and converted into a recording studio.

He said that he had "spent half of [his] life in recording studios with no windows, no light, but on the boat there are many windows, with beautiful scenery on the outside".

Other notable examples can be seen in New York's Botanical Gardens and El Dorado apartment building, and in St John's College, Hong Kong.

Crittall-style doors in a domestic setting

While Crittall doors are often associated with high society, they blend effortlessly into domestic settings.

Draughty Crittall doors are a thing of the past. They're now made with energy-efficient materials and can be double- or triple-glazed.

They're also highly secure. Wall-length windows can worry some customers, but our Crittall-style doors are made of toughened glass and fitted with multi-point locking. Their multi-framed design also helps to protect the glass.

Whether you're looking for a patio door, a partition between rooms or an eye-catching extension, Crittall-style doors provide a touch of effortless, minimalist class.

A beginner's guide to casement windows

Mon, 03 Jul 2023 11:54:38 GMT

Casement windows are a classic choice for many homes. Learn more about their advantages – and how we can help you to install, repair or replace them.

Casement windows are one of the most popular choices for homes in the UK. Chances are that you or someone you know already has one – two or more frames hinged on the outside that open outwards.

They've changed a lot over the centuries, but these days are usually made out of uPVC or aluminium. They're highly regarded for their security, energy efficiency and ability to quickly ventilate a room.

Like many windows, there are variations on the classic design. Awning casements, for instance, are hinged at the top and hoppers are hinged at the bottom.

Then there are fixed casement windows – these are purely decorative and can't be opened. They're used to show off a striking view. The same is true of casement picture windows, which are usually flanked by functioning casements to allow for ventilation.

Finally, there are French casement windows – these open like French doors without a mullion divide (the vertical strip that separates window units).

Whichever way you slice it, casement windows are a solid choice for your home . But before we look in more detail at their advantages, let's throw these windows open wide and explore their rich history.

A very brief history of casement windows

For many centuries, pretty much all windows were casement windows – at least until the sash came along.

In Shakespeare's time, casements and windows were synonymous. When Bottom in A Midsummer Night's Dream says that "the moon may shine in at the casement", he's not being overly pedantic about window styles.

Back then, the frames were mostly fashioned out of iron by local blacksmiths. It was nigh on impossible to make large sheets of glass, so casements usually consisted of six panes separated by lead strips.

Come the Victorian times, iron had been replaced by timber – especially oak – and lead strips were replaced by glazing bars.

Casement windows are often used in films to signify excitement and possibility. You can see them in Oliver! (1968), bursting open dramatically as the milkmaid sings "Who Will Buy?"

They're beloved by poets too. There's a reason Keats wrote about "magic casements, opening on the foam / Of perilous seas" and not, say, bay windows.

It was around this time that Gothic elements were introduced. Arched window tops allowed casement windows to have more than six panes and a wider range of shapes and styles.

You'll have noticed, however, that most of today's casement windows have two rather than six or more panes of glass. That's because of advances in glass manufacturing, which meant that bigger sheets of glass were possible.

Materials changed as well as styles. At the end of the 19th century, oak got replaced by softwood, which had to be painted.

There was a time when it looked as though casements were on their way out, superseded by sash windows. But they've made a comeback and are now one of the most popular of all window designs.

Today's casement windows combine that classic look with modern advances in thermal efficiency and maintenance. Where older examples were hard to clean, draughty and prone to rotting, casements on the market nowadays have all the style but none of these problems.

What are the advantages of casement windows?

Nowadays, most casement windows are made out of either aluminium or uPVC. These are extremely low-maintenance and can be decked out with a wide range of finishes.

They're easy to clean. No matter how high up they are, you can open them from the inside and easily reach most stains. This outward-opening design also means they don't clutter up your room when open.

They're the best type of window for ventilation, providing far better control of airflow than flush windows.

But they're also great at keeping the heat in, as the closing mechanism creates an airtight seal. Generally speaking, they let out far less air than sliding windows when closed.

Like all good windows, they keep cold air out and warm air in. This means they're in line with modern standards of thermal efficiency, making them good for the environment and your energy bills.

They're also highly secure. Modern casement windows come with multi-point locking and toughened glass as standard.

Finally, they're easy to customise. A good dealership will offer a host of materials, colours and designs – so you can be sure your window will add character and personality to your home.

Learning the lingo

So you know your frame from your pane, but how about your Astragal bar from your transom?

Astragal bars : these are positioned on the window's glazing on both the outside and the inside. This gives a single pane of glass the look of multiple pieces of glazing.

Flush casement windows : these have an older style, where the window looks flat against the frame when closed – as opposed to modern casements, which have a protruding "lip".

Georgian bars : unlike Astragal bars, these are set inside the sealed unit between layers of glazing.

Transom : this is a horizontal supporting strip that runs across the top or bottom of the window.

Trickle vent : this is comprised of an external grill and an internal closing vent that together lead to better ventilation and less condensation.

About our range of casement windows

10 amazing conservatories from around the world

Mon, 03 Jul 2023 11:48:19 GMT

Thinking of getting a conservatory and looking for inspiration? Join us as we take a look at 10 of the world's most amazing specimens.

If you have a conservatory or are thinking of getting one installed, you probably have one of two functions in mind.

You could be a green-fingered gardener looking for a space to grow luscious, sun-hungry plants.

Or you could have your heart set on a sunroom – an extra space in your home that bridges house and garden, drenched in natural light.

Whatever your plan is, you might know that conservatories come in a wide variety of styles, materials and finishes. There's the classic Victorian design with its geometrical bay front and ribbed, steeply pitched roof – the kind of extension that makes your home look like part of a botanical garden.

For lower buildings like bungalows, there are lean-tos. Their flatter, single-slant roofs give a more modern but no less appealing look.

But as with everything in life, there are conservatories and then there are conservatories .

A conservatory is an architect's dream. That's because the architect's materials aren't limited to glass, uPVC , aluminium and tiles. They're also working with nature – sunlight, flowers and plants.

There are some show-stopping conservatories dotted around the world that amply demonstrate just how much potential for beauty these conservatories have.

And while you might not have the budget to install a scale replica of Kew Gardens, they might just give you some inspiration.

1. Kiseki No Hoshi Greenhouse, Hyōgo, Japan

Also known as the Miracle Planet Museum of Plants, the Kiseki No Hoshi Greenhouse in Hyōgo is one of the largest in Japan. It's treated visitors to a beautiful array of rare tropical plants since it opened in 2000.

As well as its main display of vibrant flora, the greenhouse also has a fern room, small gardens, succulents and flower shows.

2. Conservatory of Flowers, San Francisco, USA

San Francisco's Conservatory of Flowers is a national landmark – and it's popular with shutterbugs for a reason. Its elaborate wooden arches, glass walls and imposing dome are hard to ignore.

It's as hardy as a cactus, having survived two fires, an earthquake and a wind storm.

Film buffs might recognise it from a cameo in Hitchcock's Vertigo (1958).

3. Muttart Conservatory, Edmonton, Canada

Architect Peter Hemingway knew how to make Edmonton's public gardens and greenhouses stand out. Instead of drawing on the Victorians for inspiration, he turned his attention to the pyramids.

The four hothouse pyramids at Muttart Conservatory are the stars of the show. They host lilies, palms, banana trees, the bird of paradise and more.

The "tropical" pyramid features a waterfall splashing into a pool where fish swim and lilies float. It used to be home to a kiwi bird and a sloth.

4. Enid A. Haupt Conservatory, New York, USA

New York's botanical gardens are a direct descendant of their English counterparts – the Big Apple's very own Crystal Palace.

Its pavilion and dome, made from steel and glass, feature aquatic plants and vines, cacti, tropical plants, towering palms and more.

It was built between 1899 and 1902 by the city's Department of Parks and Recreation – but it takes its name from benefactor Enid Annenberg Haupt, who saved it from demolition in the 1970s with a gift of $10 million.

5. Curitiba Botanical Gardens, Brazil

Jardim Botânico de Curitiba is a park in Curitiba – the capital of Paraná and southern Brazil's biggest city.

Like New York's botanical gardens, it looks to Europe for inspiration. The gardens are laid out in a French style, while the principal greenhouse looks like London's Crystal Palace has been transplanted to Brazil.

This greenhouse covers 458 square metres and features a carpet of flowers as well as the tropical plants you'd expect. Outside, there's a pond where you can see carp, turtles and herons.

6. Eden Project, Cornwall, England

The Eden Project isn't strictly a conservatory, but it serves the same purpose as the others in this list – to protect and show off a swathe of rare plants.

Built in an old clay pit, its two giant thermoplastic domes house the world's largest indoor rainforest and a Mediterranean biome.

While the design of the other greenhouses in this list could inspire your own extension, this one is strictly for the plant-lovers.

7. Schönbrunn Palm House, Vienna, Austria

When it was built in 1882, the Schönbrunn Palm House in Vienna's Palace Park was the largest in the world – a glasshouse that's around 111 metres long, 28 metres wide and 25 metres high.

It was commissioned by Emperor Franz Joseph and built to impress. Today, it's no less extravagant – a showcase for tropical plants, fruit trees and flower displays.

Its paths contain a number of semi-hidden surprises including a selection of carnivorous plants.

8. Lalbagh, Bangalore, India

Lalbagh's iron-pillared glasshouse is a product of British colonialism in India. Another descendant of the Crystal Palace, it was built to mark Queen Victoria's grandson's visit to Bangalore in 1891.

Now known as "the Jewel of the Garden City", it's used for flower shows – both permanent features and temporary shows on Republic Day (January 26) and Independence Day (August 15).

9. Gardens by the Bay, Singapore

In Singapore's Central Region, there are three waterfront gardens that together make up the Gardens by the Bay.

They're home to the Flower Dome, listed by the Guinness Book of World Records as the largest greenhouse in the world. It covers 1.2 hectares or three acres. That's equivalent to three NFL football fields.

Walking into the Flower Dome, you're entering a Mediterranean climate, stuffed with exotic flowers and planets from five of the world's seven continents.

10. Bicentennial Conservatory, Adelaide, Australia

Nicknamed "the giant pasty", Adelaide's sparkling, curvilinear conservatory is one of the sights that greets you as you fly into the city.

It's a home away from home to plants from northern Australia, Papua New Guinea, Indonesia and the Pacific Islands, many of which are endangered.

How can I make my conservatory roof quieter?

Mon, 03 Jul 2023 08:00:00 GMT

Conservatories can be great places to relax – but they often let in lots of outside noise. Join us as we look at 5 ways to keep your conservatory quiet.

Whether you use your conservatory to entertain, unwind, grow plants or watch the birds in your feeders, you're going to want a space that's quiet as well as warm.

But traditional conservatories have a drawback. They tend to let in unwanted noise from the outside and bleed noise from the inside. This isn't just annoying for you – it can also be a pain for your neighbours.

The issue is especially apparent in conservatories fitted with polycarbonate or glass roofs . A bit of rain can turn your garden retreat into an acoustic war zone – and here in Britain, there's no predicting when it might strike next.

It's a common complaint among conservatory owners, but one that's often overlooked at the planning stage. Customers are often hot on thermal efficiency but a little quiet when it comes to sound insulation.

Luckily, you've got several options for ensuring peace and quiet in your extension. You can muffle the sound inside with blinds, rugs and cushions. You can upgrade the glass to double or triple glazing. Or you can go the whole hog and get a tiled roof installed.

Whatever option you go for, it can be advisable to contact a local conservatory specialist to talk you through the process. It's going to cost you – so you need to make sure you get the quality of work you deserve.

1. Install blinds

Blinds are there to keep out light, of course – but they're also good at muffling unwanted sounds. While they don't provide a complete soundproofing solution, they can form an important part of one.

Common sense might tell you that you need to invest in a heavy-duty blind – but in fact, thinner products will do the job nearly as well.

Blinds with especially good noise reduction properties include pleated or honeycomb blinds and Roman blinds. You could also look into installing shutters, or a combination of blinds and shutters.

Blinds are versatile, too. Not only do they help to turn down the natural volume, but they also help to keep you cool during hot spells. Keeping out the sun can stop your flooring and furniture from fading too fast, as well as reduce glare.

With such a range of styles on offer, they're also a great way to add extra personality to your extension and create a cosy, inviting, and – above all – quiet atmosphere.

Finally, if you dislike the feeling of being seen, blinds can add a touch of privacy and security.

2. Install sound absorbers

Carpets are great sound absorbers – far more so than laminate flooring or tiles.

Of course, you may not want a carpet stretching to the edge of your garden. If that's so, you could invest in a large, thick rug.

Sofa cushions and throws are also good for soaking up some of the unwanted sounds.

As with blinds, these accessories can add a touch of style and personality to your conservatory while simultaneously dampening the noise. Together, they can turn a cacophony of rain into a smooth, soothing ambient soundtrack.

3. Get double or triple glazing

Glass is integral to the look and style of a conservatory – but unlike the rest of your house, it lacks the sound-absorbing properties of brick and internal insulation. That can sometimes lead to a conservatory that feels more like a cave – all echoes and wintry damp.

It doesn't have to be like this. Adding a layer or two of glass can make a huge difference. As well as ensuring peace and quiet, double or triple glazing adds value to your home and helps to regulate temperatures.

And it pays off in the long run, as you'll use less energy to heat your extension.

4. Replace your conservatory roof

This is a big job – but it's the number one way to reduce noise pollution in your conservatory.

A solid tiled roof beats its polycarbonate or glass equivalents hands down in the loudness wars. And like blinds, it can do double duty keeping your conservatory warm as well as peaceful.

If you feel like your conservatory is an ice-box in winter and a sauna in summer, a tiled roof is the way to go.

Long-lasting, fully insulated and plastered, tiled roofs regulate temperatures all year round.

What's more, they're a piece of cake to clean and reduce the chances of mould, condensation and drafts in your extension.

And with a range of finishes available, you can get a roof installed that catches the eye and blends in perfectly with the rest of your property.

5. Get a roof lantern installed

A roof lantern is essentially a 3D roof light. It provides natural light and warmth – and adds vintage elegance too.

The pitch of a roof lantern means that rain and hail slide off naturally, so you're no longer listening to the meteorological equivalent of the musical Stomp .

These glazed structures are prized for their Victorian charm – but nowadays, they're manufactured to modern standards of thermal efficiency, security and durability.

So if you want visual appeal, heat retention and noise reduction in one tasteful package, you could always consider a roof lantern.
